In
music, a step, or conjunct motion,
[Bonds, Mark Evan (2006). ''A History of Music in Western Culture'', p.123. 2nd ed. .] is the difference in
pitch between two consecutive
notes of a
musical scale. In other words, it is the
interval between two consecutive

In music theory, the scale degree is the position of a particular note on a scale relative to the tonic, the first and main note of the scale from which each octave is assumed to begin. Degrees are useful for indicating the size of intervals and ...
s. Any larger interval is called a skip (also called a leap), or disjunct motion.
In the
diatonic scale
In music theory, a diatonic scale is any heptatonic scale that includes five whole steps (whole tones) and two half steps (semitones) in each octave, in which the two half steps are separated from each other by either two or three whole steps, ...
, a step is either a
minor second (sometimes also called ''half step'') or a
major second (sometimes also called ''whole step''), with all intervals of a
minor third or larger being skips. For example, C to D (major second) is a step, whereas C to E (
major third) 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.
Half steps
In the
major scale 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.

may be characterized by its degree and type of conjunct and disjunct motion. For example,
Medieval plainchant melodies are generally characterized by conjunct motion with occasional thirds, fourths, and generally ascending fifths while larger intervals are quite rare though octave leaps may occur between two separate
phrases.
Renaissance melodies are generally characterized by conjunct motion, with only occasional leaps of more than a
fifth and then rarely anything but a sixth or
octave
