I wrote this one as an experiment in creating a melody flow that would require a sour note to sound right. I’ve always been fascinated by intentional discord and transient harmonics that must pass through unpleasant chord/note combinations to get from where it starts to where it wants to go.

Listen for the sour note. You’ll hear it, and also understand why it is part of the required progression for the melody to work.

Composed and recorded in the early 1970s.
