The short version
- Amaj7 is A major seventh. Its notes are A, C♯, E and G♯ (formula 1 – 3 – 5 – 7).
- Easiest way to play it: the open shape, frets x 0 2 1 2 0 from low E to high E (x = don’t play).
- It sounds dreamy, jazzy, sunset-in-a-convertible. Swap it in for any I or IV chord in a major key when the song needs to sound expensive.
- Amaj7 turns up in 4 keys: A major (as the Imaj7), E major (as the IVmaj7), F♯ minor (as the IIImaj7) and C♯ minor (as the VImaj7).
- Try it in: Amaj7 – Dmaj7 – Amaj7 – Dmaj7, a two-chord dream-pop vamp you can loop forever.
How to play Amaj7 on guitar, step by step
Start with the shape marked “Start here” above: the open chord, the easiest way in.
- Put your index finger on fret 1 of the 3rd (G) string.
- Put your middle finger on fret 2 of the 4th (D) string.
- Put your ring finger on fret 2 of the 2nd (B) string.
- Let the A and high E strings ring open.
- Don’t play the low E string: skip it, or touch it lightly with a spare finger so it can’t ring.
- Strum from the 5th (A) string down, then press Strum on this page to check it sounds the same.
Once that’s comfy, try the other shape. Shape 2 is the movable shape, root on the 6th string (5th fret): 5 x 6 6 5 x. Same chord, different spot on the neck, which helps when the next chord lives nearby.
Buzzing? Press just behind the fret wire, not in the middle of the fret, and come down on your fingertips so they don’t touch the next string. Then press Strum and play along: if yours sounds duller, one string is muted somewhere.
