About this chord
The half-diminished chord (ø7) combines a diminished fifth and a minor seventh. It is the chord on degree II of the harmonic minor scale, central to the ii°7–V7–Im jazz cadence. On guitar, its compact voicings often overlap with m6 shapes, making them easier to memorize and use together.
