ukulele scale
E♭ double harmonic
Two augmented seconds in one scale, one above the tonic and one below the octave.
The same sounds spelled from the other side are D♯ double harmonic.
Written out
Every accidental is written in, rather than left to a key signature, so the letters can be read one at a time.
The step pattern
What is true of it
E♭ double harmonic is E♭, F♭, G, A♭, B♭, C♭ and D, and back to E♭.
Its steps are H – W+H – H – W – H – W+H – H, where W is a whole step and H a half.
On the same tonic, E♭ harmonic major differs from it by exactly one note.
Across the first twelve frets of the ukulele its notes fall in 30 places, which is what makes a scale a shape rather than a list.
