The A diminished chord (A dim or A°) contains the notes A, C and Eb. It is produced by taking the 1st, flat 3rd and flat 5th notes of the A 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 diminished chord contains a tritone between the notes A and Eb.

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 flat 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 Bb Major chord and hear for yourself how this sounds
