Learn how to use the Locrian #2 (half-diminished scale) sound for m7b5 (half-diminished) chords —quickly!
In this Quick Tip, John Proulx breaks down the scale and explains the easy shortcut to find it: go up a minor 3rd and play melodic minor (e.g., Dø7 → F melodic minor) to unlock smooth lines, avoid harsh b9 clashes, and flow into V7alt → minor i.
You’ll also get plug-and-play locrian #2 licks and a backing track for the minor 2–5–1 (iiø–V7alt–i). Perfect for jazz standards and minor blues.
