I took a beginner music theory class and there was a quiz on reading music notation.
H W H W H W W W W W
I got 8 of them right. I got the 4th and 10th bar wrong. I wrote it's a whole step (W) for both, but the answer key says it's a half-step (H) for both.
4th measure:
E# and Eb
F and Eb (there is no E#, I assume it's F)
I do 2 half steps (from F to E, and from E to Eb) which is a whole step
10th measure:
Bb and B#
Bb and C (I assume there is no B# and replaced it with C)
I do 2 half steps (from Bb to B, and from B to C) which is a whole step
Feel free to correct my terminology.
("hs" on the pictures stands for "half step")
