What is true of it
A Dorian is A, B, C, D, E, F♯ and G, and back to A.
Its steps are W – H – W – W – W – H – W, where W is a whole step and H a half.
On the same tonic, A natural minor differs from it by exactly one note.
Across the first twelve frets of the ukulele its notes fall in 32 places, which is what makes a scale a shape rather than a list.
