How to play B7
- Middle (2) on the 5th string, fret 2 (B).
- Index (1) on the 4th string, fret 1 (E♭).
- Ring (3) on the 3rd string, fret 2 (A).
- Little finger (4) on the 1st string, fret 2 (F♯).
- Let string 2 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.
