Dominant Bebop

Mixolydian + chromatic between ♭7 and root, every key

Same idea as the major bebop scale, but built on the V chord. The dominant bebop scale is mixolydian (the natural mode of V) with one added chromatic — the natural 7 inserted between ♭7 and the octave-root. Eight notes per octave, chord tones on every strong beat.

Played over V7 in a ii–V–I, this scale gives you eight notes to choose from for every downbeat; the chord tones (1, 3, 5, ♭7) will land where the ear expects them. Together with the major bebop scale, this is the melodic backbone of Parker-onwards single-line vocabulary.

Now 2 octaves, both hands — the same pattern extended up and back with fingering marked above every note in each hand.

The Daily Drill

Pair with the major bebop

4 minPlay both scales back-to-back in one key: the I major bebop and the V dominant bebop. Notice the ♯5 in the major bebop where the dominant bebop has a ♭7 — that's the only note difference (the major 7 is in both scales).
10 minCycle through three V chords at a time. Each scale fits its target V7 perfectly; the chromatic falls exactly between ♭7 and root.
3 minPlay the I bebop, then immediately the V dominant bebop, then back to I. Practice the modal switch with the metronome on quarters.
3 minImprovise a V-I phrase using only these scales. The ♭7 of V resolves to 3 of I (the iconic dominant resolution); land on the 3 on beat 1.

Why the chromatic goes between ♭7 and root

For the chord tones of V7 (1, 3, 5, ♭7) to land on the four strong beats over eight eighth notes, the scale must have exactly eight notes per octave. Mixolydian only has seven (1-2-3-4-5-6-♭7-1). Adding a natural 7 (between ♭7 and the next root) gives the eighth note in the right spot. Different chord → different chromatic position; same architectural rule.

Same logic as the major bebop, voiced over the dominant. Two scales, the entire bebop vocabulary.
