Tip: click any note, key or fret to hear it. Orange = root.

3Indications: what it is used for

Mixolydian plus the major seventh as a passing note (1-2-3-4-5-6-♭7-7). It is played over dominant seventh chords in bebop, swing, hard bop and jazz blues, and over the ii–V pair (since ii and V share the same parent scale). Played descending from a chord tone on a downbeat in continuous eighth notes, the chromatic step keeps the chord tones (1, 3, 5, ♭7) on the beats, which is why it sounds so idiomatic in fast swing tunes.

4Dosage: how to practise it

Ten minutes daily at 100–200 BPM with a swing feel. Start descending from the root on beat one in steady eighth notes and check that every downbeat falls on 1, ♭7, 5 or 3. Then start from the third, fifth and seventh. Practise ii–V–I lines combining a ii arpeggio with descending bebop runs. On guitar, use positions that keep the chromatic step on one string. On piano, use the right hand for lines and left-hand shells (3 and ♭7). Increase the tempo by 8 BPM per week.

5Warnings and common mistakes

The added major seventh is a passing note only: landing on it on a strong beat over a dominant chord sounds wrong. The scale works best descending in eighth notes starting on a chord tone; starting off the beat shifts the chromatic note onto downbeats. Do not confuse it with the major bebop scale (major scale plus ♯5/♭6). Over altered dominants, the natural ninth and thirteenth clash; switch to altered or diminished there.
