B to C, but not A to B
Answer:
SEMITONE
Hint:
This musical interval is the smallest distance between two adjacent notes on a piano, like moving from a white key to the very next black or white key.
Explanation:
This clue plays on musical intervals—the distance between two notes. "A to B" is a whole tone (two semitones), but "B to C" is just a semitone (the smallest step in the standard Western scale). The "but not" hints that the answer is the smaller of the two, so "semitone" fits perfectly.
