Who invented the notes

Even people who are far from musical notation will not hesitate to name you seven musical notes: do-re-mi-fa-sol-la-si. This very simple combination of sounds is so consonant that it resembles a funny song. What is most interesting is that this is the song, or rather the anthem ... but let's go in order

It is interesting that the impetus for the development of music in this direction was given by church choirs. Until the 11th century, parchment was used to record parchment - signs in the form of dashes and dots, indicating where to emphasize when singing church psalms. Naturally, such a chaotic chanting system had a lot of shortcomings. Nevmas were entered into special catalog books, where their decoding was given, there was no question of memorizing all nevmas.

Modern musical notation dates back to the writings of the monk Guido Arezzo (circa 991-1033), who began writing notes in the form of filled squares on a four-line stave. The names of the musical scale - from "to" to "si" - denoted the first syllables of the words of the prayer to John the Baptist, which was used for chanting in the church choir. It contained a request to preserve the power of the voice: "Give us a clean mouth, Saint John, so that we can bear witness to the miracles of your deeds with all the power of our voice":

Ut queant laxis

resonare fibris,

Mira gestorum

famuli tuorum,

Solve polluti

labii reatum,

Sancte Ioannes.

If we discard unnecessary words, then we see the first two syllables in the first six lines: ut, re, mi, fa, sol, la. The note ut was subsequently replaced by do, since it is much more convenient to start singing with a consonant letter. Obviously, this note is named after God, in Latin it sounds like Dominus.

But what about the SI note? It's simple - the capital letters of the words of the last line of the prayer form the final SI musical note.
