Eb composite blues

The composite blues scale merges the major and minor blues scales into one nine note super set: root, 2nd, both 3rds, 4th, flat 5th, 5th, 6th, flat 7th. It is less a scale to run than a map of every blues inflection available in one key: major sweetness, minor grit and the blue note all coexist. Blues and jazz players effectively think in it already.

it consists of these notes and degrees:

F

IV

bV

tip
  • Do not run all nine notes: treat Eb composite blues as a map and pick the major-blues subset over I and IV, minor-blues subset over V.
  • Practice switching mid-phrase: answer a line built on II, bIII (Gb), III, VI with one built on IV, bV (A), V, bVII (Db).
  • The double chromatic runs (II-bIII-III and IV-bV-V) are built-in slurs: hammer through them landing on the chord tone.
  • Over a shuffle in Eb, keep strong beats for triad tones and spend all that chromatic wealth on the upbeats.

How to play E♭ composite blues on guitar

Closest root is fret 1 on the D string, so low playing starts one fret from the nut despite the six-flat spelling. Open G rings the major third and open A the flat fifth, which means the only two open strings you get are both core scale tones. Capo at fret 1 and everything reads as D. A-shape barre sits at fret 6, E-shape at fret 11, and the first box stretches all the way to fret 15.
