D-sharp minor

What it means

D-sharp minor is the minor key built on the root D♯. On the circle of fifths it sits six steps to the sharp side of C major or A minor, and its key signature has six sharps: F♯, C♯, G♯, D♯, A♯, and E♯.

Enharmonically, D-sharp minor is identical to E-flat minor, which is notated with six flats. On any equal-tempered instrument the two keys sound exactly the same, differing only in spelling and, as a result, in how easily the music reads.

In the notation

The key signature of D-sharp minor consists of six plain sharps: F♯, C♯, G♯, D♯, A♯, and E♯. Unlike its enharmonic relative D-sharp major, D-sharp minor needs no double sharps and is therefore considerably easier to read, though it is still encountered less often than its flat-key counterpart.

Musical use

Since E-flat minor, with six flats, is considered equally common and similarly legible, composers usually favor E-flat minor, especially within pieces dominated by flat keys. D-sharp minor tends to appear instead as a brief passing key inside works built around sharp keys, for instance during modulations coming from a key already far on the sharp side.
