C♯6

C♯1E♯3G♯5A♯6

A major triad with a sixth added. The same four notes as a minor seventh chord a third below.

Written the other way round it is D♭6 — the same twelve keys on a piano, a different piece of notation.

What is true of it

C♯6 is C♯, E♯, G♯ and A♯ — 1, 3, 5 and 6 counted from C♯.

These are also the notes of A♯m7/C♯ and B♭m7/C♯. Which name is right depends on what is underneath and what came before — the notes alone do not decide.

On an instrument that cannot reach all 4, the 5 goes first, in that order.

The easiest of the 5 fingerings below is x111: one finger, one of them barring the 1st fret, held at the 1st fret.

None of them uses an open string, so this chord moves up the neck unchanged — the same shape 1 fret higher is the chord a semitone above.

2 of the 5 need a barre.

It leaves out the 5. 4 strings cannot carry 4 notes, and the 5 is the one this chord can lose without changing what it is.

1 string stays silent.

The brass dots are C♯, the root. Everything else is a chord tone with its degree printed in it.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
