Same notes, different home note
Db diminished whole-half uses exactly the same notes as C diminished half-whole, Eb diminished half-whole, E diminished whole-half, F# diminished half-whole, G diminished whole-half, A diminished half-whole and Bb diminished whole-half. What changes is the note the music keeps returning to, and with it which chord sounds like home.
How Db 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 Dbdim7 (Db Fb G Bb) 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 E, G and Bb.

What this page cannot do
- One spelling per scale. C# diminished whole-half is the same sounds written from C#; 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.
