What is a hexachord in music?
Hexachord, in music, six-note pattern corresponding to the first six tones of the major scale (as, C–D–E–F–G–A). The hexachord was described in medieval and Renaissance musical theory and was extensively used in the teaching of singing.
Does hexachord have intervals?
In simplest terms, a hexachord is a set of six notes arranged to form intervals of two whole-tones, a central semitone, and two more whole-tones. We may represent this arrangement as T-T-S-T-T, with “T” standing for a whole-tone (Latin tonus), S for a semitone (semitonium).
What is a Guidonian note?
The idea of the Guidonian hand is that each portion of the hand represents a specific note within the hexachord system, which spans nearly three octaves from “Γ ut” (that is, “Gamma ut”) (the contraction of which is “Gamut”, which can refer to the entire span) to “E la” (in other words, from the G at the bottom of the …
What made a hexachord soft?
A melody moving a semitone higher than la (namely, from A to the B♭ above) required changing the la to mi, so that the required B♭ becomes fa. Because B♭ was named by the “soft” or rounded letter B, the hexachord with this note in it was called the hexachordum molle (soft hexachord).
