Common card · No. 318689

D-flat major is a major scale based on D♭, consisting of the pitches D♭, E♭, F, G♭, A♭, B♭ and C. Its key signature has five flats. The D-flat major scale is: Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The D-flat harmonic major and melodic major scales are: Its relative minor is B-flat minor. Its parallel minor, D-flat minor, would feature a B (B-double-flat) in its key signature, and is usually written as the enharmonic key of C-sharp minor, with only four sharps. The enharmonic equivalent of D-flat major is C-sharp major. In music for the harp, D-flat major is preferred enharmonically not only because harp strings are more resonant in the flat position and the key has fewer accidentals, but also because modulation to the dominant key is easier (by putting the G pedal in the natural position, whereas there is no double-sharp position in which to put the F pedal for G-sharp major).
