The half diminished scale is a seven-note musical scale. It is more commonly known as the Locrian ♮2 scale,[1] a name that avoids confusion with the diminished scale and the half-diminished seventh chord (minor seventh, diminished fifth). It is the sixth mode of the ascending form of the melodic minor scale (or jazz scale).

In the key of C, the half-diminished scale built on D is associated with Dm7♭5, which functions as a iiø7 chord in minor (see chord-scale system).

The Locrian ♮2 scale is commonly used in jazz and some rock. It is commonly practiced by such neoclassical metal guitarists Michael Romeo, and such jazz pianists as Oscar Peterson and Jonah Cristall-Clarke.
