Other ways to play C♯7

C♯7 the capo way

No barre needed if a capo is allowed: capo on the 1st fret and play the open C7 shape (0-0-0-1), capo on the 2nd fret and play the open B7 shape (2-3-2-0), capo on the 4th fret and play the open A7 shape (0-1-0-0) or capo on the 6th fret and play the open G7 shape (0-2-1-2). The chord sounds as C♯7 because the capo raises every string by a half step.

A short C♯7 drill

Pick shape 1 one string at a time, low to high: G♯, C♯, E♯, B. Every note should ring clearly; if one thuds, adjust that finger before you strum. Then switch to 4-5-4-4 and back four times without looking at your hand.
