In music, a scale is a group of musical notes collected in ascending and descending order, that provides material for or is used to conveniently represent part or all of a musical work including melody and/or harmony. Scales are ordered in pitch or pitch class, with their ordering providing a measure of musical distance. The term scale is also used to mean the abstracted intervalic structure or shape of a collection of notes independent of the actual pitches used, as in "major scale", which invokes the particular structure common to the C-major scale, D-major scale, etc.
