C#aug7 Ukulele Chord

C#aug7 gathers C#, F, A, and B into a tense dominant color, its sharpened fifth giving the chord a jazzy, off-balance bite. It works beautifully as a leaning V chord in jazz and funk, eager to resolve down a step into something darker.

How to Play This Chord

Position your fingers on the fretboard as shown in the diagram. The vertical lines represent the four strings, from the top G string (left) to the A string (right), and the horizontal lines are the frets. Numbers inside the dots indicate which finger to use: 1 (index), 2 (middle), 3 (ring), 4 (pinky). An X means don't play that string; an O means play it open. A bar spanning multiple strings means one finger presses across all of them at once — this is known as a barre chord.

Tips & Tricks

Barre your index finger flat across the C and E strings at fret 1, then add your middle finger on the G string at fret 2 and your ring finger on the A string at fret 2. The half barre tends to mute the E string — roll the index slightly onto its side and check both inner strings ring.
