The Dm7b5 chord (D minor 7 flat 5, or D half diminished) contains the notes D, F, Ab and C, which is the 1 (root) b3, b5 and b7 of the D Major scale. It can be viewed as a Dm7 chord with a flat 5 or a D 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. Dm7b5 is the 7th chord in the key of Eb Major. Try playing an Eb chord, then a Dm7b5 chord and then return to Eb. This is an example of how Dm7b5 can sound beautiful in context.

The Dm7b5 chord is most commonly played with the root note on the 3rd fret of the 5th string (2nd shape in the picture below).
