Standard tuning, high e on top as in tablature, open strings to fret 12. Every dot is a note of the scale; the pattern repeats from fret 12 up.
Chords that fit D diminished half-whole
Every chord of the common types (triads, sus, sixths, sevenths, add9, 7b9, 7#9) whose notes are all in the scale, on each of its notes, spelled as on the chord pages. A 8-note scale has no single set of "the" chords the way a seven-note scale does.

Same notes, different home note
D diminished half-whole uses exactly the same notes as C diminished whole-half, Eb diminished whole-half, F diminished half-whole, F# diminished whole-half, Ab diminished half-whole, A diminished whole-half and B diminished half-whole. What changes is the note the music keeps returning to, and with it which chord sounds like home.
How D diminished half-whole is built
Eight notes, alternating a semitone and a whole tone, starting with the semitone. Because the pattern repeats every three semitones, the same eight notes are also the half-whole scale on F, Ab and B; there are only three different diminished scales in all. Jazz players use this one over a dominant seventh with a flat or sharp 9th: D7, D7b9 and D7#9 all sit inside it, as the chord list below shows.

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.
