How to play C♯7
- Lay your index finger flat across fret 4, from the 5th string to the 1st string (the barre).
- Ring (3) on the 4th string, fret 6 (A♭).
- Little finger (4) on the 2nd string, fret 6 (F).
- 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.
No barre yet? Put a capo on fret 1 and play the open C7 shape — it sounds as C♯7. Work out other positions with the capo calculator.
