Scale (music) scale is often used. In jazz, many different modes and scales are used, often within the same piece of music. Chromatic scales are common, especially in modern jazz. In Western music, scale notes are often separated by Equal temperament tones or semitones, creating 12 intervals per octave each separating two tones where the higher tone has a oscillation frequency of a fixed ratio (by a factor equal to the twelfth root of two, or approximately 1.059463) higher than the frequency of the lower one. A scale uses a subset consisting typically of 7 of these 12 as scale steps. Other
Harmonic major scale Harmonic major scale In music theory, the harmonic major scale is a musical scale found in some music from the common practice era and now used occasionally, most often in jazz. It was named by Rimsky-Korsakov. In George Russell's "Lydian Chromatic Concept" it is the fifth mode (V) of the Lydian Diminished scale. It can be considered a major scale with the sixth degree lowered, Ionian 13, or the harmonic minor scale with the third degree raised. It may also be generated by reversing and rotating the succession of intervals in the harmonic minor scale. It contains the following chords,
