The Dbm7b5 chord (D flat minor 7 flat 5, or D flat half diminished) contains the notes Db, Fb, Abb and Cb, which is the 1 (root) b3, b5 and b7 of the Db Major scale. It can be viewed as an Dbm7 chord with a flat 5 or a Db diminished chord with an added b7.

The half diminished chord can sound like a very dissonant chord, when played in isolation. However, when played in the context of other chords, it can sound beautiful. Try playing a D chord, then a Dbm7b5 chord and then return to D. This is an example of how Dbm7b5 can sound beautiful in context.
