Dot Porter did a more thorough tour of MS Codex 1248 today compared to our prior glimpse.
Today I learned that the phrase “run the gamut” comes from Γ ut or gamma ut, which is the lowest note of the hexachord system on the Guidonian hand and is also used to describe all the possible notes.
And for some somewhat related musical fun via John Carlos Baez:
Guillaume Dufay (1397 – 1474) is the most famous of the first generation of the Franco-Flemish school. (This first generation is also called the Burgundian School.) He is often considered a transitional figure from the medieval to the Renaissance. His isorhythmic motets illustrate that—their tonality is dissonant and dramatic compared to typical Renaissance polyphony.
