Every accidental is written in, rather than left to a key signature, so the letters can be read one at a time.

EWF♯HGHG♯W+HBWC♯W+HE

E major blues is E, F♯, G, G♯, B and C♯, and back to E.

Its steps are W – H – H – W+H – W – W+H, where W is a whole step and H a half.

Across the first twelve frets of the ukulele its notes fall in 26 places, which is what makes a scale a shape rather than a list.

Found by testing every chord in the catalogue against these 6 sounds, not chosen.
