The A sharp diminished chord (A# dim or A#°) contains the notes A#, C# and E. It is produced by taking the 1st, flat 3rd and flat 5th notes of the A sharp Major scale.

A diminished often appears as A# dim or A#°.

The diminished chord played by itself has a dissonant sound. This is largely due to the existence of the tritone interval, which is otherwise known as the devil’s interval. The A sharp diminished chord contains a tritone between the notes A# and E.

Even though the A# diminished chord sounds dissonant on its own, it can sound beautiful when played in the right context. Pairing the A# diminished chord with the B Major chord, for example, creates a sense of tension and release, which works well. A good exercise is to switch between the A# diminished chord and the B Major chord and hear for yourself how this sounds
