Viewing music in colour, a musical colour scheme
The colour music tone progression up and down the scale, and associate it with the sound. The colour is assigned the notes of the scale—C, D, E, F, G, A, B, C—a syllable: Do, Re, Mi, Fa, Sol, La, Ti, Do.
The sounds came from “Ut Queant Laxis,” a hymn of the Middle Ages that was chanted for vespers. Each succeeding line of the song started one note higher than the previous one, so the first letters of each word of each line: UT queant laxis, REsonare fibris: MIre gestorum , FAmuli tuorum: SOLve, etc. “Ut” was eventually deemed too difficult pronounce and was changed to “Do.”
