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
Bebop scale Harris. Ben-Hur further elaborates on the concept of placing additional chromatic passing tones between other notes in the scales. The bebop harmonic minor scale (or bebop natural minor scale, as listed in Mark Levine's "The Drop 2 Book") is derived from the harmonic minor scale and has a chromatic passing tone (an additional 7) between the 6th and the 7th notes. \override Score.TimeSignature #'stencil = ##f \relative c' { </score> It contains all of the notes of both the harmonic minor scale and the natural minor scale (Aeolian mode) of the same root.
