What is the Half-Whole Diminished scale?
The half-whole diminished scale alternates half steps and whole steps across eight notes. It supplies the flat ninth, sharp ninth, sharp eleventh and thirteenth over a dominant chord, which makes it the standard altered dominant sound in jazz.
A Half-Whole Diminished is a scale, not a key. It has no key signature of its own — music that uses it is normally written in the key signature of its parent scale, with any extra accidentals added as they occur.
