Piano: Eb Blues Over the Changes

Where Eb Blues lies at this seat, and what a chorus takes out of it.

Eb Blues runs 6 notes to the octave, laid out here across 88 keys with every Eb flagged. Mid-chorus the pattern is not what you need; where the root is when the chord changes underneath you is.

The minor pentatonic with a b5 "blue note" wedged in — that one extra note adds grit, tension, and a sly, vocal quality. Tough, expressive, and unmistakably bluesy.

Heard in: Blues, rock, jazz, rhythm and blues, and boogie-woogie — Delta and Chicago blues, Hendrix, Clapton, Stevie Ray Vaughan.

The right hand takes the line and the left keeps stating the chord under it, which makes a scale at this seat a two-handed problem: the notes have to work against a voicing you are choosing at the same time.

Play it slowly against the audio until it stops being a shape, then put it over two bars of a form and let the chord tones decide which of the notes you actually keep.
