How to play C♯add9, step by step

  1. 1Lay your index finger flat across all six strings at the 9th fret — this is the barre, and it works like a movable nut.
  2. 2Put your ring finger on the 11th fret of the A string (5th).
  3. 3Put your little finger on the 11th fret of the D string (4th).
  4. 4Put your middle finger on the 10th fret of the G string (3rd).
  5. 5Strum 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.

An easier way to play C♯add9

C♯add9 normally needs a barre, which is the single most common place beginners stall. A capo removes it entirely.

Put a capo on fret 1 and play an open Cadd9 shape. The capo raises every string by 1 semitone, so what your hand fingers as Cadd9 comes out of the guitar as C♯add9 — the same chord, none of the strain.
