Pentatonic
A pentatonic scale is a scale with 5 tones per equave. It is one of the most commonly used types of scale in the world. The familiar major and minor pentatonic scales are modes of the 2L 3s mos scale.
Pentatonic mos scales may be found at Pentatonic MOS. Other pentatonic scales may be found at Category: 5-tone scales.
Equipentatonic scales are scales with 5 roughly equally spaced tones per octave, common in some musical traditions. The exactly equal form of the equipentatonic scale is 5edo.
5 equal frequency divisions instead of pitch gives a pentatonic overtone scale, the first mode of 5afdo.
Pentatonic scales may sometimes be used as chords rather than scales, in which case they are called pentads.
