Musical Scales

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.[1] Scales are ordered in pitch or pitch class, with their ordering providing a measure of musical distance. The distance between two successive notes in a scale is called a scale step. - Wikipedia
