A '''scale''' is a sequence of [[pitch]]es. Each of these pitches is a '''tone''' (not to be confused with other meanings of the term ''[[tone]]''). Each tone can be identified by its '''degree''', its position in the scale, and is often expressed as the [[interval]] it makes with the '''[[tonic]]''', the first tone of the scale. The interval between two consecutive tones is a '''step'''.

Scales are typically organized in ascending or descending order. In most scales, the descending form is identical to the ascending form but in the opposite order. However, some scales have different forms in both directions, such as the [[Wikipedia:Melodic minor scale|melodic minor scale]]. A '''reentrant scale''' features at least one '''negative step''', going backwards relative to the general direction of the scale. Although a reentrant scale is not strictly ascending or descending, its ascending and descending forms are determined by its general direction.
