Answer:
More generally, a step is a smaller or narrower interval in a musical line, and a skip is a wider or larger interval with the categorization of intervals into steps and skips is determined by the tuning system and the pitch space used.
In the language of music theory, a step is the distance between notes of different pitches. A half step, or semitone, is the smallest interval between notes in Western music. Notes that are directly next to each other—such as E and F, or A sharp and B—are a half step apart.
