C#6 Ukulele Chord
C#6 is the C sharp sixth chord. It has four notes: C sharp, F, G sharp and A sharp. The main shape is the straightest line on the neck: every string at the 1st fret, four fingers or one flattened index.
Every string at the 1st fret: four staggered fingertips, or one finger laid flat. The straight line sixth at its lowest position.
How to play C#6 on ukulele, step by step
- Index finger: 1st fret, G string
- Middle finger: 1st fret, C string
- Ring finger: 1st fret, E string
- Pinky finger: 1st fret, A string
- Strum all four strings.
The chart prints four fingers, but every note sits at the 1st fret, so many players simply lay the index flat across all four strings. That flat finger version is also D6 one fret lower: the straight line sixth slides.

If it sounds muddy or buzzy
- Four fingers will not fit at one fret
- Stagger them diagonally so each tip takes its own string, or switch to one finger laid flat across all four. Both are correct; use whichever sounds cleaner.
- The flat finger buzzes
- The 1st fret is the stiffest place for a barre. Keep the finger right behind the fret wire, roll it slightly onto its edge, and squeeze from the thumb behind the neck.
- The outer strings are quiet
- The g and A strings sit under the weakest parts of a flat finger. Strum slowly and listen for all four notes before playing in time.
What makes it a C#6
C♯ · F · G♯ · A♯ 1 3 5 6
C#6 is a C sharp major triad (C sharp, F, G sharp) with a sixth added: the A sharp, nine half steps above the root. The third of C sharp is strictly E sharp, which is the same key as F, and chord charts write F because that is the name players read fastest.
The same four notes read from A sharp spell Bbm7. A ukulele has no bass string to choose between the names, so the chords around it choose instead.
C#6 vs C#maj7
C#6 adds an A sharp to the C sharp triad; C#maj7 adds a C, sitting a half step under the root. The sixth rests where the major seventh hovers.
C sharp is usually met as D flat in horn and piano charts. Either spelling, the sixth is the version that closes a phrase without pushing anywhere.
