How to use the D♭m7♭5 chord

The D♭m7♭5 chord is built from a root, a minor third, a diminished fifth and a minor seventh. Start at the root D♭ and stack the intervals to get the whole chord: D♭, F♭, A𝄫 and C♭. The same formula gives you the chord in any other key.

Half-diminished chords are most common in jazz standards. They frequently act as the iiø of a minor ii-V-i, leading into the dominant that resolves to a minor tonic.

How D♭m7♭5 differs from similar chords

D♭m7♭5 differs from D♭m7 by one lowered note, the fifth, and from D♭°7 by one raised note, the seventh. That in-between position is where the name half-diminished comes from. In a minor key it is the ii chord, so it almost always leads to a dominant seventh.
