Quote: In music, a scale is a set of musical notes that provides material for part or all of a musical work. Scales are typically ordered in pitch, with their ordering providing a measure of musical distance. Scales differ from modes in that scales do not have a primary or "tonic" pitch. Thus a single scale can have many different modes, depending on which of its notes is chosen as primary. Every note in a scale is referred to as a scale degree. The distance between two successive scale degrees is called a "scale step." Composers often transform musical patterns by moving every note in the pattern by a constant number of scale degrees: thus, in the C major scale, the pattern C-D-E ("doe, a deer") might be shifted up a single scale degree to become D-E-F ("ray, a drop"). Since the steps of a scale can have various sizes, this process introduces subtle melodic and harmonic variation into the music. This variation is what gives scalar music much of its complexity. Scales may be described according to the intervals they contain, for example • diatonic, chromatic, whole tone or by the number of different pitch classes they contain: • most common: pentatonic, hexatonic, heptatonic or five, six, and seven tone scales, respectively. • used in prehistoric music: ditonic or two, tritonic or three, tetratonic or four • in modern classical music: octatonic or eight. Scales are often abstracted from performance or composition, though they are often used precompositionally to guide or limit a composition. One or more scales may be used in a composition, such as in Claude Debussy's L'Isle Joyeuse. Below, the first scale is a whole tone scale, while the second and third scales are diatonic scales. All three are used in the opening pages of Debussy's piece.
