Every accidental is written in, rather than left to a key signature, so the letters can be read one at a time.

What is true of it
D minor pentatonic is D, F, G, A and C, and back to D.
Its steps are W+H – W – W – W+H – W, where W is a whole step and H a half.
It uses no sharps and no flats at all: seven letters, seven white keys.
Across the first twelve frets of the ukulele its notes fall in 23 places, which is what makes a scale a shape rather than a list.
