D-flat minor is a theoretical key based on the musical note D♭. Its key signature has seven flats and one double flat.
Because it has so many flats, D♭ minor is usually written as its enharmonic equivalent of C♯ minor. For example, Mahler's thematic motif "der kleine Appell" ("call to order") from his Fourth and Fifth Symphonies is written in D♭ minor in Symphony No.4, but in his Symphony No. 5 it is in C♯ minor. In the Adagio of his Symphony No. 9 a solo bassoon theme appears first in D♭ minor, but comes back two more times notated in C♯ minor. The Adagio of Bruckner's Symphony No. 8, also has phrases that are tonally in D♭ minor but written as C♯ minor.
