What is true of it
B major is B, C♯, D♯, E, F♯, G♯ and A♯, and back to B.
Its steps are W – W – H – W – W – W – H, where W is a whole step and H a half.
On the same tonic, B melodic minor differs from it by exactly one note.
Across the first twelve frets of the ukulele its notes fall in 29 places, which is what makes a scale a shape rather than a list.
