What is true of it
D harmonic minor is D, E, F, G, A, B♭ and C♯, and back to D.
Its steps are W – H – W – W – H – W+H – H, where W is a whole step and H a half.
On the same tonic, D natural minor differs from it by exactly one note.
Across the first twelve frets of the ukulele its notes fall in 31 places, which is what makes a scale a shape rather than a list.
