How to play C♯dim, step by step

  1. 1Put your index finger on the 4th fret of the A string (5th).
  2. 2Put your middle finger on the 5th fret of the D string (4th).
  3. 3Put your little finger on the 6th fret of the G string (3rd).
  4. 4Put your ring finger on the 5th fret of the B string (2nd).
  5. 5Leave the low E and high E strings out — mute them with the side of a finger, or just avoid them as you strum.
  6. 6Strum slowly and check every string sounds cleanly; if one buzzes, press closer to the fret wire and arch your fingers so they clear the neighbouring strings.
