The short version
- A5 is A five. Its notes are A and E (formula 1 – 5).
- Easiest way to play it: the open shape, frets x 0 2 2 x x from low E to high E (x = don’t play).
- It sounds loud, neutral and heavy. Use it with distortion, palm-muted, sliding up and down the neck. On a clean guitar it sounds a little bare, which can be the point.
- A5 turns up in 12 keys: C major (as the VI5), G major (as the II5), D major (as the V5), A major (as the I5) and E major (as the IV5), and more in the table below.
- Try it in: A5 – G5 – D5 – A5, the riff your neighbours already know through the wall.
How to play A5 on guitar, step by step
Start with the shape marked “Start here” above: the open power chord, the easiest way in.
- Put your index finger on fret 2 of the 4th (D) string.
- Put your middle finger on fret 2 of the 3rd (G) string.
- Let the A string ring open.
- Don’t play the low E, B and high E strings: skip them, or touch them lightly with a spare finger so they 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 power chord, root on the 6th string (fret 5): 5 7 7 x x 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.

|---|---|---|
