Tips for playing C♯aug on guitar
On guitar, the usual C♯aug shape is x-x-11-10-10-9 at the 9th fret. It has no open strings, so it’s a movable shape — slide it along the neck for other augmented chords. Don’t strum the low E and A strings.
Notice the E♯ in C♯aug (C♯ E♯ G𝄪): each note of the chord takes its own letter (C–E–G), so the major 3rd has to be written E♯ rather than F — the same key on a piano, spelled to fit the chord.
