The Asus2 chord on acoustic guitar

Quality: Suspended 2 · Root note: A · Difficulty: Beginner

How to read this diagram

The six vertical lines are the strings of the guitar — leftmost is the low E (the thickest string), rightmost is the high e (the thinnest). The horizontal lines are the frets, with the nut (or your capo, if you're using one) at the top. Filled dots are where your fingers go. The numbers inside the dots are which finger to use: 1 = index, 2 = middle, 3 = ring, 4 = pinky. An open circle above a string means strum that string open. An × means don't play that string at all — either skip it with your pick or mute it with the side of a finger.

How to play Asus2 step by step

1. Mute the low E string — don't let it ring out.
2. Let the A string ring open.
3. Place your index finger on the D string at fret 2.
4. Place your middle finger on the G string at fret 2.
5. Let the B string ring open.
6. Let the high e string ring open.

Once your fingers are placed, pluck each string of the chord one at a time — slowly. Every note should ring cleanly. If one buzzes or sounds muted, look at the finger above it: it's almost always a fingertip touching a neighboring string, or a knuckle that's collapsed flat instead of arched. Adjust, then try again.

Common mistakes with Asus2

The most frequent issue learners encounter with this shape is unintended muting of adjacent strings. Your fingers need to come down on their tips, not their pads, so that each fingertip presses only one string. The second most common issue is not pressing hard enough — push down close to (but not on top of) the metal fret bar to get a clean tone with the least force. If your hand is sore after a minute or two, you're almost certainly squeezing too hard.

The third issue is more subtle: the thumb. If you find that the high E or B string isn't ringing out, check whether your fretting-hand thumb is wrapped over the top of the neck. Drop it down behind the neck, roughly opposite your middle finger, and the chord will instantly open up. This applies to nearly every open chord on the guitar — if a shape feels cramped, it's almost always thumb position.

How Asus2 is built

The Asus2 chord is a suspended 2 chord built on the root note A. Sus2 chords replace the 3rd of a chord with the 2nd. They're neither major nor minor — they sound open, ambiguous, slightly chiming. Often used as a colorful pass-through chord between two regular chords. Understanding what's inside the chord doesn't help your fingers — but it helps your ears, which is what eventually lets you hear a chord progression and know which shape to reach for.
