What is true of it
B Dorian is B, C♯, D, E, F♯, G♯ and A, and back to B.
Its steps are W – H – W – W – W – H – W, where W is a whole step and H a half.
On the same tonic, B natural minor differs from it by exactly one note.
Across the first twelve frets of the guitar its notes fall in 47 places, which is what makes a scale a shape rather than a list.
