The half diminished scale is a musical scale more commonly known as "Locrian 2",[1] name which avoids confusion with the diminished scales (see octatonic scales) and the half-diminished seventh chord (min. 7, flat 5). It may be considered Mode VI, the sixth mode, of the ascending melodic minor scale. See: jazz scale.

In the key of C, the half-diminished scale built on D is associated with Dmi75, which functions as a iiø chord in minor. See: chord-scale system.

Applications

Locrian 2 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.

The half diminished scales, although derived from classical scales, offer new potentials in modern harmonic and melodic structure.
