'''Parallel motion''' is motion in the same direction, keeping the same interval between them. For example {{audio|ParallelMotion.mid|Play}}:

Parallel motion at an interval of a [[perfect fifth]] is known as parallel or [[consecutive fifths]], and at an interval of an [[octave]] is known as parallel or consecutive octaves. Perfect intervals, i.e. the (perfect) unison, fifth and octave, are generally avoided in traditional [[counterpoint]] because they offer the lines so little independence from each other.{{sfn|Laitz|2012|pp=52, 113}}

In [[Counterpoint#First species|first-species counterpoint]], it is recommended to limit parallel thirds or sixths to three consecutive uses of a given intervallic size.{{sfn|Laitz|2012|pp=52, 55}} 

Chords between which all [[Factor (chord)|factors]] or voices move in parallel motion are called ''parallel chords''.{{sfn|Benward|Saker|2009|p=358|loc="Parallel chords"}} This motion is called [[Planing (music)|planing]].{{sfn|Benward|Saker|2009|p=14}}
