) is a skip. 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. Melodic motion in which the interval between any two consecutive pitches is no more than a step, or, less strictly, where skips are rare, is called ''stepwise'' or ''conjunct'' melodic motion, as opposed to ''skipwise'' or ''disjunct'' melodic motion, characterized by frequent skips.

or any of its modes, a step will always be a movement of 1 or 2 semitones, and a skip a movement of 3 or more semitones. In other scales an augmented second—an incomposite step equivalent to 3 semitones—and/or a diminished third—a skip of 2 semitones—may be possible.
