How to use the Dm7♭5 chord
The Dm7♭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.
In major keys Dm7♭5 is the viiø7 in E♭ major; in minor keys it's the iiø7 in C minor.
How Dm7♭5 differs from similar chords
Dm7♭5 differs from Dm7 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.
Where Dm7♭5 is used
A half-diminished seventh has one main use: it is the ii of a minor key, leading into the dominant. A major key builds the same chord on its seventh degree.
