A-sharp minor

A sharp minor is a key of the tonal family minor, which is built on the root a sharp. The key of A sharp minor is written in musical notation with seven sharp accidentals (F sharp, C sharp, G sharp, D sharp, A sharp, E sharp, H sharp). The corresponding scale and the fundamental chord of this key (the tonic a sharp-c sharp-e sharp) are also designated by the term a sharp minor.

Because of the seven accidentals (one could represent A sharp minor - enharmonically reinterpreted - more simply with B flat minor), this key has presumably only been used by Johann Christian Heinrich Rinck in his 30 two-part exercises through all keys.
