== Dividing the perfect fourth into more parts ==
A scale segment spanning a perfect fourth can also contain more than 4 notes; for example, a segment with 5 notes is called a '''pentachord''', a segment with 6 notes a '''hexachord''', etc. These are useful in larger scales, such as the decatonic scales of [[pajara]] temperament. In particular, the ''pentachordal'' decatonic scale contains two equal pentachords and a 9/8 interval split into two semitones.
