How to play A7
- Index (1) on the 4th string, fret 2 (E).
- Middle (2) on the 2nd string, fret 2 (C♯).
- Let strings 5, 3, 1 ring open.
- Strum from the 5th string down; don’t play string 6.
- Pick the strings one at a time: each note should ring clearly — if one buzzes, move that finger closer to the fret.
Once the open shape is comfortable, try the barre version at fret 2: same chord, higher voice, and a shape you can move all over the neck.
