A♯m7

A♯1C♯♭3E♯5G♯♭7

Minor triad with a minor seventh. The same four notes as a major sixth chord a third above.

Written the other way round it is B♭m7 — the same twelve keys on a piano, a different piece of notation.

What is true of it

A♯m7 is A♯, C♯, E♯ and G♯ — 1, b3, 5 and b7 counted from A♯.

These are also the notes of C♯6/A♯ and D♭6/A♯. 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 3544: 4 fingers, held at the 3rd 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.

The brass dots are A♯, 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.
