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
Synthetic scale By adding a G to the scale, one would end up with the LydianVII, the fourth degree of the Melodic Minor scale. The pitches of synthetic scales may duplicate pre-existing scales, though their derivation is different and their use is often quite different. Synthetic scale In music, a synthetic scale is a scale that derives from a traditional diatonic major scale by altering of one degree by a semitone in either direction. Composer Ferruccio Busoni originally explored these scales in his "A New Esthetic of Music" and their number and variety were later clarified by J. Murray Barbour, who also
