Same notes, different home note
D diminished whole-half uses exactly the same notes as Db diminished half-whole, E diminished half-whole, F diminished whole-half, G diminished half-whole, G# diminished whole-half, Bb diminished half-whole and B diminished whole-half. What changes is the note the music keeps returning to, and with it which chord sounds like home.
How D diminished whole-half is built
Eight notes, alternating a whole tone and a semitone, starting with the whole tone. It holds the diminished seventh chord Ddim7 (D F Ab B) plus the note a whole tone above each of its notes, which is why it is the scale played over a diminished seventh chord. Its notes repeat every three semitones, so it is also the whole-half scale on F, G# and B.

What this page cannot do
- One spelling per scale. the root is spelled the way that needs the fewest sharps and flats.
- Equal temperament only. Blues and many folk traditions bend notes between these pitches, and Arabic and Turkish maqam scales use quarter tones that a piano cannot play.
- The guitar diagram shows standard tuning only and does not suggest fingerings; any note can be played in several places.
- The sound is a simple synthesised tone made in your browser, not a recorded instrument.
