How to Play the A7sus4 Guitar Chord (Even With One Finger)

To play A7sus4 on guitar, mute the 6th string (low E), let the 5th (A) string ring open, put your index finger on the 2nd fret of the 4th string (D), your middle finger on the 2nd fret of the 3rd string (G), and lay your ring finger across the 2nd and 1st strings (B and high E) at the 3rd fret. That is the full, four-note open shape, the same one Oasis use in "Wonderwall." There is also a genuinely easier version that needs only one finger, covered below, because most of what you will find searching this chord online disagrees with itself about which notes actually belong in it.

The open A7sus4 shape, string by string

Here is the full shape as a table. "Finger" uses standard numbering: 1 is your index finger, 2 is your middle finger, 3 is your ring finger, 4 is your pinky.

Build it from the bottom string up. Anchor your index finger on the D string first, since it sits at the lower of the two fretted positions and sets your hand's overall angle. Add your middle finger on the G string at the same fret. Then lay your ring finger flat across the B and high E strings at the 3rd fret, forming a small two-string barre, the same technique used for the sibling shape on this site, Dsus4. Your ring finger only needs to cover those two strings, not the whole neck.

This gives you all four notes that make A7sus4 what it is: A (the root, ringing open on the 5th string and doubled on the G string at the 2nd fret), E (the 5th, on the D string), D (the 4th, on the B string), and G (the flat 7th, on the high E string). The exact note map, and how it compares to a plain A chord, is covered in the theory section further down.

Which strings to strum

Strum from the 5th string (A) down through the 1st string (high E). That is five strings total. The 6th string (low E) is not part of this chord and needs to stay out of the strum entirely, not just played quietly underneath everything else.

If the low E string rings along, you get a note that sits a perfect 4th below the chord's actual root, and it turns a clean, tense suspended sound into a muddy low rumble that fights with the A string right above it. It will not sound like an obviously wrong note, more like a chord that never quite focuses, which is exactly the kind of vague wrongness that sends beginners hunting for a fretting mistake when the real issue is the pick's starting point.

Two ways to keep the low E string out of the sound:

• Anchor your strum on the A string. Aim your downstroke so the first string your pick or thumb makes contact with is the A string, not the low E. This takes deliberate aim for the first week or two and becomes automatic after that.
• Rest the underside of your fretting-hand index finger lightly against the low E string as it reaches down to the D string. Because the index finger's first knuckle sits just above the low E on this shape, a slight lean is often enough to deaden it without you having to think about a separate muting motion.

Test this deliberately. Strum slowly and listen to the very first sound your pick makes contact with. If you hear a low, dull thud before the rest of the chord rings out, that is the low E string sneaking into the strum, and it is worth isolating before you build any speed around it.

The one-finger version, and why it is not a shortcut

Here is the detail almost every chord chart for this shape misses entirely: A7sus4 can be played with a single fretted note.

Mute the low E string, let the A, D, and G strings ring open, fret only the B string at the 3rd fret, and let the high E string ring open too. Strum from the A string down. That single fretted note, D, is enough to complete the chord: the open strings already give you A (root), D (4th), G (b7), and E (5th), so the one fretted note is only adding a second D an octave higher, not filling in a note that was otherwise missing.

This is not a simplified stand-in for the "real" chord the way some easier fingerings are. It contains every note the four-finger version does, root, 4th, 5th, and flat 7th, just with fewer of them doubled. The difference between this and the fuller shape further up this page is voicing, which notes ring twice, not which notes are present at all. If your hand is not ready for a two-string barre yet, this version is not a compromise, it is a complete A7sus4.

An in-between version, with two fretted notes

If the one-finger shape feels too sparse and the barre still feels early, there is a middle option.

Add your index finger on the D string at the 2nd fret to the one-finger shape above, and you get a slightly fuller sound without touching the barre at all. This voicing turns up on more than one reputable chord chart as its own named position, distinct from both the one-finger version and the full barre version, which tells you the three-way split in difficulty here is real, not something this page invented to pad out a beginner section.

Which version should you actually use

All three open voicings above are correct A7sus4 chords, so the choice comes down to what you need in the moment, not which one is more "real."

If you are learning this chord for the first time, start with the one-finger version so your hand can focus entirely on muting the low E string and aiming the strum correctly, without a barre competing for attention. Add the index finger for the two-finger version once that feels automatic, and only reach for the full barre version once both simpler shapes are solid. Skipping straight to the barre is the single most common reason beginners give up on this chord early, when a note-complete, correctly named version of it was available the entire time with a fraction of the difficulty.

Why so many chord charts for this shape disagree with each other

If you searched for this chord before landing here, you likely ran into two or three fingering diagrams that do not agree, some of them even contradicting their own note lists. That is a real, common problem with this specific chord, not a sign you are reading something wrong.

The most frequent error: a chart lists A7sus4's notes correctly as A, D, E, and G, then gives a fingering that frets the G string at the 2nd fret, turning that open G note into an A. Do that and the chord loses its flat 7th entirely, the G note, which is the one thing that separates A7sus4 from a plain Asus4. The result still sounds fine on its own, but it is not the chord the page claims to be teaching, and if you are trying to match a recording that specifically uses the fuller, darker A7sus4 sound, that fingering will sound thinner than what you are hearing.

The fingering given at the top of this page, and cross-checked against Oasis's actual "Wonderwall" chord charts and an independent voicing database, keeps the G string open specifically so the flat 7th survives. If you see a diagram elsewhere that frets the G string at the 2nd fret for A7sus4, that shape is playing Asus4 with a doubled A, not A7sus4, regardless of what it is labeled.

What makes a chord "suspended," and where the "7" comes from

A regular A major chord is built from three notes: A (the root), C# (the major 3rd), and E (the perfect 5th). That middle note, the 3rd, is what tells your ear whether a chord is major or minor. A suspended chord drops that note and replaces it with either the 2nd or 4th degree of the scale instead. A7sus4 replaces it with D, the 4th, which is where "sus4" comes from.

The "7" adds one more note on top: G, a whole step below the root, known as the flat 7th (or minor 7th). Stack that onto a plain Asus4 (A, D, E) and you get A7sus4 (A, D, E, G), four notes instead of three.

Because there is no 3rd, A7sus4 is neither major nor minor. It sits in a kind of harmonic limbo, wanting to resolve, and in the vast majority of real songs it resolves down a half step from D to C# by moving to a plain A chord, or it slides to D itself, since D is already sitting right there in the chord.

A7sus4 vs A7 vs Asus4 vs Asus2

These four chords share most of their notes and get mixed up constantly, so it helps to see them side by side.

A7sus4 is the only chord in this table with both a suspended 4th and a flat 7th at once, which is what gives it a fuller, slightly darker tension than plain Asus4. Compared to A7, the difference is a single note: C# swapped for D. On the fretboard that is the B string, fretted at the 2nd fret for A7 and one fret higher, at the 3rd fret, for A7sus4. The clearest way to hear the difference is to play A7, then A7sus4, then back to A7, keeping every other finger still and only moving the one on the B string, and listen for that note sliding between C# and D.

Why your A7sus4 is buzzing or sounds dead

A buzz or a muted, thuddy note in this chord almost always comes from one of six specific causes. Work through them one at a time.

Your index finger is lying too flat

If your index finger rests flat instead of coming down close to vertical on its tip, the pad of that finger can brush the string next to it and choke a note your other fingers are trying to produce. Curl the finger more so it contacts the D string only at the very tip, arching up and away from the G string beside it.

The ring finger barre is uneven

Barring two strings only works if the finger applies even pressure across both at once. New players often press harder on the string closer to the palm and let the other one go slack. Roll your ring finger very slightly toward its outer edge, which is flatter and firmer than the fleshy center of the fingertip, and you will get a more even bite on both the B and high E strings.

You are pressing in the middle of the fret space instead of behind the wire

Fret numbers count the space between two metal fret wires, not the wire itself. A finger pressed in the middle of that space, or up near the wire behind it, needs noticeably more force to avoid a buzz than one pressed right against the fret wire on the side closer to the guitar's body. Move your index finger, middle finger, and ring finger barre until each sits just behind its fret wire and check whether the same pressure now produces a clean note.

Not enough downward force on the barre

Even with good placement, the ring finger barre needs continuous, even pressure that holds for the entire time you strum, not just the first instant. New players' hands tire quickly holding any barre, because the muscles used for it are not yet built up. Fret the two-string barre on its own, pick each string individually, and add pressure gradually until both ring out clean. This improves with repetition, not with a different technique.

Your thumb has crept over the top of the neck

If your thumb rides up and over the top edge of the neck instead of staying behind it, your whole hand flattens to compensate, which flattens the index and middle fingers along with the barre. Keep your thumb low on the back of the neck, roughly behind the gap between your index and middle fingers, and all three contact points arch more without you having to think about them separately.

The open A string is getting muted by accident

Because your index finger sits on the string directly below the open A string, it is easy for the side of that finger to lean back and deaden the A string without you noticing. Pick the open A string on its own while your hand holds the A7sus4 shape and confirm it rings exactly as it does with your fretting hand off the guitar. If it sounds shorter or duller, straighten the angle of your index finger slightly until the A string clears completely.

The movable barre version, for playing A7sus4 anywhere on the neck

Once the open shape feels solid, a movable version lets you play the same chord quality, root, 4th, 5th, flat 7th, from a shape you can slide up and down the neck. The most common form sits at the 5th fret.

Barre your index finger across all six strings at the 5th fret. Add your ring finger on the A string at the 7th fret, and stretch your pinky up to the 7th fret on the G string. Strum all six strings.

This shape is moveable. Slide the whole hand shape up two frets to the 7th position and you get Bsus4-with-a-7th (B7sus4), up two more to the 9th position and you get C#7sus4, and so on, the root note always sitting on the fret your index finger barres on the 6th string.

Changing from A7sus4 into other chords

Outside of its relationship with plain A, A7sus4 shows up as a passing or connecting chord on the way to several other common shapes. A few of the moves worth drilling on their own:

A7sus4 to A. Your ring finger barre releases, and that same finger drops down one fret, from the two-string barre at the 3rd fret to a single note on the B string at the 2nd fret, the note that fills in the missing 3rd (C#). The high E string, no longer barred, rings open. Since the index and middle fingers stay exactly where they are, this is one of the smallest possible resolutions in the whole suspended-chord family.

A7sus4 to D. Because D is already one of the notes ringing inside A7sus4, this change feels more connected than it looks on paper. Your index finger slides from the D string over to the G string at the 2nd fret, your middle finger moves from the G string over to the high E string at the 2nd fret, and your ring finger narrows its barre down to just the B string at the 3rd fret, releasing the high E string so your middle finger can take it.

A7sus4 to Em. Almost the entire hand relaxes. Em only needs two fingers, on the A and D strings at the 2nd fret, both lower down the neck than anything A7sus4 uses. This is one of the easiest transitions in this family, since you are moving from a busier shape to a simpler one.

A7sus4 to G. This is a bigger reshuffle. Your ring finger barre releases entirely, your index finger moves down to the low E string at the 3rd fret, and the rest of the hand rebuilds around it. Slow this one down and isolate it before trying it inside a full strum pattern.

A7sus4 to Dsus4. These two chords share the note D and the general "unresolved" quality, and pairing them is common in songs that stack multiple suspended chords in a row. The full Dsus4 fingering is worth having solid before chaining the two together at tempo.

For any of these, practice the change alone first: fret A7sus4 clean, strum once, then move to the target chord and strum once, without the pressure of any surrounding rhythm. Once that jump is reliable at a slow, steady pace, add the rest of the song's chords back in around it.

The A7sus4 to A7 move, a blues staple

Outside of resolving to plain A, A7sus4 has a second, closely related job: resolving to A7 instead. This is a common move on the V chord of a 12-bar blues in the key of D, where the turnaround briefly suspends the dominant chord before letting its 3rd back in.

The move itself is small. From the full A7sus4 shape, lift your middle finger off the G string entirely and let it ring open, dropping the b7 back to what becomes the missing note of a plain A7 for a moment. Then drop your ring finger from its two-string barre down one fret, from the 3rd fret to the 2nd fret, on the B string alone, and let the high E string ring open. Your index finger does not move at all. What was A7sus4 a moment ago is now A7: A, C#, E, G.

Played as a quick figure, A7sus4 landing on beat one and A7 landing right after, this is the same tension-and-release relationship that Dsus4 has with D, just applied to a dominant 7th chord instead of a plain major triad. It shows up constantly in blues and blues-rock rhythm playing specifically because the V chord in a 12-bar blues is already a dominant 7th, so suspending it and releasing it back adds a second layer of tension right where the progression is already asking to resolve.

Where A7sus4 fits in the key of D

In the key of D major, the chords built from the scale are D, Em, F#m, G, A, Bm, and F#°, the I through vii° chords. A7sus4 is not one of those seven scale chords in the traditional sense, since it is built by altering the A7 chord itself rather than stacking thirds on a different scale degree. A sits at the V position in the key of D, so A7sus4 functions as a decorated version of the dominant chord, delaying its pull back to D by a beat or two before letting the 4th resolve down into the 3rd.

A common pattern in the key of D goes G, D, A7sus4, A, or Em7, G, D, A7sus4, letting the suspended chord act as the last stop before the progression lands back on D. This is close to the exact function A7sus4 plays in "Wonderwall," where it follows Em7, G, and Dsus4 before the progression loops back to the start.

A7sus4 also shows up built directly on the tonic, inside the key of A itself, rather than only as a borrowed dominant color from the key of D. Played as the very first or last chord of a song in A, it works as a color on the I chord, delaying the plain A major sound by a beat the same way Dsus4 delays D in its own key. The blues turnaround covered earlier is really this same idea applied to A7 instead of plain A, since A7 is itself the dominant chord of D, and suspending it briefly before releasing it back adds tension right where a blues progression is already asking for release.

Progressions that use A7sus4 well

A few chord progressions come up often enough with A7sus4 that they are worth having under your fingers as complete patterns, not just the A7sus4-to-A move in isolation.

None of these need anything beyond the shapes already covered on this page. What changes from one progression to the next is only the timing, how many beats each chord gets before the next change, and that is worth working out by ear against whatever recording you are actually trying to learn.

Songs that lean on A7sus4

A7sus4 is common enough in pop and rock guitar parts that you have almost certainly heard it before recognizing it by name.

Oasis's "Wonderwall" is played with a capo on the 2nd fret, and its verse cycles through Em7, G, Dsus4, and A7sus4, in that order, before repeating. It is the single most widely learned example of this chord, and the fingering at the top of this page is the exact shape used in that song's chord charts.

Pink Floyd's "Wish You Were Here" also uses A7sus4, cycling through Em7, G, and A7sus4 across its opening acoustic riff before the vocal enters. Unlike "Wonderwall," where A7sus4 is the last stop in a four-chord loop that keeps moving, here the riff returns to A7sus4 repeatedly without a Dsus4 or plain A in between, which makes it a good second reference for hearing the chord's tension on its own rather than as a quick passing stop.

Both are worth learning specifically because they use the chord the way it is meant to be used, a passing color that adds tension next to nearby chords, rather than a chord sitting on its own for a long stretch with nothing around it. Since "Wonderwall" uses a capo, remember that the shape you are fretting is still A7sus4, only the pitch that actually sounds has shifted up by the capo.

A strumming pattern that uses the Wonderwall progression

The verse pattern from "Wonderwall," Em7, G, Dsus4, A7sus4, translates well into a basic pop strum you can use on any song built around a similar four-chord loop: down, down-up, up-down-up, repeated once per chord change. Land the downstroke of beat one on the chord change itself, so the strum and the finger movement land together rather than the strum happening slightly ahead of or behind the fret change.

Because A7sus4 is the last chord in that loop before it repeats back to Em7, give it a moment to actually register as suspended before the pattern resets. Rushing straight through it undercuts the whole reason the progression uses a sus chord there in the first place, since the ear needs at least a beat to register the tension before the loop lets it go by starting over on Em7.

Start slower than feels natural, at a tempo where you can clearly hear all four chords ring before moving to the next, and only speed up once every change happens without you having to look at your hand. A muddy A7sus4, most of these chords are quick to blur under a fast strum, is almost always a sign the pattern is faster than the fretting hand is ready for, not a sign the shape itself is wrong.

Playing A7sus4 fingerstyle

Everything above assumes a strum, but this chord works just as well plucked note by note, and the shape does not change at all, only how your picking hand approaches it.

A simple pattern to start with: thumb on the open A string, then index finger on the D string, middle finger on the G string, ring finger on the B string, played one after another rather than all at once. Repeat that four-note pattern twice per chord, so it fills a full bar at a moderate tempo. Because the full shape only asks for three fretting-hand contact points, index, middle, and the ring-finger barre, both hands are free to move independently, the picking hand keeping its own steady pattern while the fretting hand only has to change once per chord.

If the full barre-style A7sus4 fingering feels like too much to manage while fingerpicking, the one-finger version covered earlier works just as well here. Thumb on A, then pluck the open D, G, and high E strings along with the fretted B string in any order, and you keep all four notes of the chord with only one finger to coordinate against your picking hand.

Using a capo with A7sus4

Every fingering on this page is a shape, not a fixed pitch, so putting a capo on the neck changes what note actually sounds without changing anything about how your hand moves. Clip a capo on the 2nd fret and play the exact same open A7sus4 shape covered at the top of this page, and you get B7sus4 at concert pitch, since the capo has raised every open string by two semitones.

This matters most when you are playing along with a recording in a key that does not have a comfortable open A7sus4 shape of its own. Rather than learning a new, harder fingering for a different suspended dominant chord, capo up or down to the fret that puts the song in A, and use the shape you already know. This is exactly what "Wonderwall" is doing: the fretting hand plays A7sus4 the whole way through that chord, while the pitch that actually sounds, because of the capo on the 2nd fret, is B7sus4.

Common mistakes with suspended chords in general

Beyond the specific buzzing causes already covered, a few habits trip up players learning sus chords as a category, not just A7sus4 specifically.

Holding the suspended chord too long. Because a sus chord has no 3rd, it does not commit to major or minor, and letting it ring on its own for several full bars starts to sound unresolved in a way that reads as unfinished rather than intentional. Most uses of A7sus4 in real songs last a beat or two before resolving, not a full measure or more.

Assuming every "sus" chord that includes a 7 is the same as a plain sus chord. As covered above, A7sus4 and Asus4 differ by exactly one note, the flat 7th, and a chart or recording that just says "Asus" without specifying is leaving out real information. If you are working from a chart that just says "sus," check a recording to hear whether that extra note is actually there before you guess.

Fretting the wrong string trying to "simplify" the shape. As covered in the section on conflicting chord charts, the single most common error with this specific chord is fretting the G string, which removes the note that makes it a 7th chord at all. If a shape you find online frets the G string at the 2nd fret, it is not A7sus4.

Practicing the shape only in isolation. A sus chord that sounds perfect on its own, held indefinitely while you check each string, can still fall apart the moment it has to arrive on beat one of a real strum pattern, because the fretting-hand movement that gets you there was never rehearsed at tempo. Once the static shape is clean, the next step is always practicing the specific move into it at the actual speed the song needs.

Left-hand position and thumb placement, the fundamentals underneath every shape above

Every fix on this page assumes a few basics about how your fretting hand sits on the neck, and it is worth checking these directly if more than one chord in this family feels consistently difficult rather than just one specific finger.

Keep your thumb low on the back of the neck, roughly opposite the gap between your index and middle fingers, rather than high near the top edge or wrapped over it. A low thumb gives your fingers a more open angle to come down on the strings from above, which is what lets them arch onto their tips instead of lying flat.

Angle your wrist very slightly outward, away from the body of the guitar, rather than keeping it perfectly straight. A completely straight wrist tends to flatten the fingers as they reach for higher strings, while a small outward angle opens up the hand's natural curl.

Keep your fretting-hand elbow reasonably close to your side rather than winging outward. An elbow that drifts away from the body pulls the whole forearm's angle out of line with the neck, which then has to be compensated for somewhere in the wrist or fingers, usually at the cost of a clean arch.

None of these are specific to A7sus4, but a barre shape like the two-string ring finger barre in this chord exposes bad hand position faster than a simple single-finger chord does, since a barre has no room for even slight flatness before a string chokes.

A short warm-up for the ring-finger barre

If the two-string barre on the B and high E strings is the one part of this chord that will not cooperate, a short dedicated warm-up before you attempt the full shape tends to help more than repeating the whole chord over and over.

Start with just the ring finger, off the guitar entirely, and press its tip against your thumb, feeling which part of the fingertip makes first contact. That same contact point, closer to the outer edge than the fleshy center, is what you want touching the strings.

Then, on the guitar, lay the ring finger flat across only the B and high E strings, at the 3rd fret, with no other fingers involved yet. Pick both strings together and listen for two clean notes rather than one clean note and one buzz. Roll the finger slightly toward its outer edge until both ring out, then relax the hand completely and repeat the whole motion from scratch, rather than holding the position and just adding pressure. Building the barre fresh each time trains the placement itself, not just the strength to force a bad placement into working.

Do ten of these clean, deliberate repetitions before adding the index and middle fingers and forming the complete A7sus4 shape. Most players find the barre noticeably easier within the same practice session once it has been isolated like this.

How A7sus4 looks in a chord chart or tab

Chord charts and diagrams describe this shape in a few different ways, and it helps to recognize all of them, since you will run into each one eventually.

A six-character string of frets, read left to right for the 6th string down to the 1st, is the most compact way to write the full shape: x 0 2 2 3 3. The "x" means the low E string is muted, the "0" means the A string rings open, and "2 2 3 3" gives the frets for the D, G, B, and high E strings in that order, which matches the table at the top of this page exactly. The one-finger version, by the same convention, is x 0 0 0 3 0.

A vertical chord diagram, the kind printed in most songbooks, shows the same information as a small grid: six vertical lines for the strings, horizontal lines for frets, dots where you press down, and an "x" or "o" above each string to show muted or open. Reading one is really just reading the table above turned sideways, string by string, fret by fret.

In a tab (the numbers-on-lines format used for single-note lines and riffs rather than strummed chords), you would see the same fretted notes stacked as a chord hit, written as a small vertical group of numbers at one point in the timeline rather than spread across a full measure, since a strummed chord in tab notation is just several notes played at the same instant.

One notation detail worth knowing specifically for this chord: some charts write it as "A7sus" without the "4," which almost always means the same chord as A7sus4, since sus2 is comparatively rare on a dominant 7th chord and most writers drop the "4" as understood. If a chart you are reading also has an A7sus2 nearby, or specifies "A9sus4," treat those as genuinely different chords rather than shorthand for the same shape.

A practice routine for today

Fifteen minutes is enough to make real progress on this chord if the time is spent deliberately rather than strumming through it and hoping it improves.

1. Two minutes: Fret the one-finger A7sus4 shape, strum once, hold, and listen. Check each string individually, low E muted with no sound at all, A, D, and G ringing open and clear, B fretted clean, high E ringing open. Reset your hand and repeat ten times.
2. Three minutes: Move to the full four-note shape. Build it from the bottom up each time, index, then middle, then the ring finger barre, rather than trying to place all three at once. Strum once, hold, listen, reset.
3. Five minutes: Practice the A7sus4 to A resolution in isolation. Strum A7sus4, move to A, strum, back to A7sus4, strum. Repeat slowly, listening for the moment the tension in the sus4 resolves into the plain major chord.
4. Five minutes: Play through the "Wonderwall" verse progression, Em7, G, Dsus4, A7sus4, at a slow tempo, using the chord in context rather than in isolation, even if you have to stop and restart at the hard parts.

Repeating this same fifteen minutes daily for one to two weeks is usually enough for the open shape to stop needing conscious thought, at which point the movable barre version becomes the next thing worth spending that same daily quarter hour on.

Frequently asked questions

Is A7sus4 hard to play? The one-finger version is one of the easiest chords on this entire site, since it only asks for a single fretted note. The full four-note version with the two-string barre is closer to a beginner-intermediate difficulty, and the movable barre version at the 5th fret is a full barre chord, worth learning only after a handful of other barre chords already feel comfortable.

Why does A7sus4 sound unfinished? Because it has no 3rd, the note that normally tells your ear whether a chord is major or minor. Without it, your ear hears the 4th degree pulling toward the 3rd it is replacing, which creates the sense of tension and expectation that gives suspended chords their name. The added flat 7th deepens that tension further, which is part of why A7sus4 is common in dominant, resolution-seeking positions in a progression.

Do I always have to resolve A7sus4 to A? No, but it is by far the most common use. Songs like "Wish You Were Here" return to A7sus4 repeatedly within a riff rather than resolving it to A every time. If you are learning it for the first time, practicing the resolution to A first will make the chord's purpose click faster.

What is the difference between A7sus4 and Asus4? Asus4 has three notes, A, D, and E, with no 7th at all. A7sus4 adds a fourth note, G, the flat 7th, on top of that same suspended structure. If a fingering online frets the G string for what it calls "A7sus4," it has likely turned the chord back into Asus4 by removing that note.

Can I strum all six strings for A7sus4? Not for the open shape at the top of this page, since the low E string is not part of the chord and adds a note that muddies the sound. The movable barre version at the 5th fret is built to use all six strings safely, since the barre itself supplies the correct low note as part of the shape.

Is the one-finger version really the same chord, or a simplified stand-in? It is the same chord. Every note in the full four-note shape is either an open string or the single fretted D note in the one-finger version, just without any of the doubling the fuller shape adds. The difference is thickness of sound, not which notes are present.

Why do different websites show different fingerings for this chord? Because the flat 7th (the G note) is easy to lose by mistake if a fingering frets the G string instead of leaving it open. A shape that frets the G string at the 2nd fret is playing Asus4, not A7sus4, even if it is labeled otherwise. Cross-check any fingering you find against the note list, A, D, E, and G, before trusting it.

Is A7sus4 the same in every tuning? No. Everything on this page assumes standard tuning, E-A-D-G-B-E from the 6th string to the 1st. In any alternate tuning, the same finger shape will produce different notes, so treat these fingerings as standard-tuning specific unless you have separately worked out the shape for whatever tuning you are using.

What does the "7" actually change if I already know Asus4? It adds one note, G, the flat 7th, without touching anything else in the chord. Every fingering adjustment on this page beyond the basic Asus4 shape exists purely to fit that one extra note in, either as an open string or as an added finger, depending on which version of the chord you are playing.

Can A7sus4 replace a plain A7 in a song? Usually only briefly. Because A7sus4 has no 3rd, it does not carry the same clear major quality A7 does, so swapping it in for an entire progression changes the character of the song rather than just adding color. Used as a quick passing chord right before or after A7, as in the blues turnaround move covered above, it works well precisely because it resolves almost immediately.

If you are still building your basic open chord vocabulary before tackling shapes like this one, Dsus4 rounds out the same suspended-chord family from a different root, and GuitarLowKey's daily lessons are built around the same fifteen-minutes-a-day approach used in the practice routine above.
