Tip: The Minor 7 b5

This chord doesn’t get a lot of press, but it’s pretty useful. We’re going to look at the min7b5 chord. First, a pattern for it:


That’s the D min7b5. And here’s an arpeggio pattern for the same chord. Use this to solo:


Where can we use the min7b5? Let’s look at three different uses: 1) replacing the dom 7, 2) replacing a tonic minor chord, and 3) in a minor ii V I progression.

Here’s an example of the first usage:


This progression is as follows: F minor 7 in bar 1, Bb7 and D min7b5 in bar 2, and Eb 6/9 in bar 3. In other words, a ii V I in Eb major.

Look at bar 2. We’re substituting the D min7b5 in place of the Bb7 here. The Bb7 was also included, so you can compare the similarity of sounds. Why do the Bb7 and D min7b5 sound alike? Look at the notes:

D min7b5: D F Ab C
Bb7: Bb D F Ab

Three notes in common definitely make for a similar sound. Next time: usage 2) replacing the tonic minor chord.

Thanks for reading.
