...it was called. Now, however, the lichanos hypaton original: "lycanos hypaton"; the "index finger string of the principal notes" is named from the others added above. In that order and arrangement, the string which was called hyphypate original: "hyphypate"; meaning "under the principal" in that division is now called lichanos; but this will appear later. Now, the order of the nine-stringed scale enneachord is as follows:

it holds itself

But the Ephesian of Colophon A reference to an ancient musician, possibly Terpander or a later theorist from Colophon adjusted the string toward the deeper part original: "in grauiorem partē". Timotheus of Miletus, however, added the eleventh string. Those strings which were added above the hypate and parhypate are called the hypate hypaton original: "hypate hypaton"; literally "the principal of the principals," representing the lowest group of notes, as if they were the greatest of the great, the deepest of the deep, or the most excellent of the excellent. The first among the eleven is called hypate hypaton. The second is parhypate hypaton, since it is located next to the hypate hypaton. The third, which was previously called hyphypate in the nine-stringed scale, is now named lichanos hypaton. The fourth held the ancient name hypate. The fifth is parhypate. The sixth is lichanos, keeping its ancient name. The seventh is the mese original: "mese"; the "middle" note. The eighth is the paramese. The ninth is the trite. The tenth is the paranete. The eleventh is the nete.

Therefore, one four-note scale tetrachord consists of the hypate hypaton, parhypate hypaton, lichanos hypaton, and hypate. Another is the hypate, parhypate, lichanos, and mese. These two are conjoined They are "conjoined" because they share a common note, the Hypate, to link them together.. The third is the paramese, trite, para-

-nete, and nete. But since between the higher tetrachord (which is hypate hypaton, parhypate hypaton, lichanos hypaton, and hypate) and the lowest one (which is paramese, trite, paranete, and nete) there is a middle tetrachord located in between (which is hypate, parhypate, lichanos, and mese), this whole middle tetrachord is called the meson The manuscript uses "melon," likely a scribal error for the Greek "meson," meaning middle. with the addition of the name: hypate meson, parhypate meson, lichanos meson, and mese.

However, because there is a separation between this middle tetrachord and the lower one (which is the tetrachord of the netas), specifically between the mese and the paramese, every such tetrachord that is separated is called diezeugmenon diezeugmenon original: "diezeugmenon"; a Greek term meaning "disjointed" or "separated" by a whole tone gap. This is noted with the addition of the names: paramese diezeugmenon, trite diezeugmenon, paranete diezeugmenon, and nete diezeugmenon. The description is in this manner:

There is, therefore, this separation between the paramese and the mese; and thus it is called the diezeugmenon tetrachord. But if the paramese is removed and the scale proceeds as mese, trite, paranete, and nete, then these will be conjoined tetrachords, called synemmena synemmena original: "sinemena"; Greek for "conjoined" or "connected". The last tetrachord will then be called synemmenon in this way:
