[Smt-talk] Seven-letter scale notation (was re: scale degrees)

[Fiona McAlpine]

Perhaps we should just get rid of Pesudo-Odo, as if he is a person, & refer to the C10th treatise Dialogus de Musica. In fact the C9th/early C10th Musica Enchiriadis uses the letters A-G as a repeating sequence; not, however, for the purpose of laying out a mode in a scalar way, but as pitch indicators in a diastemmatic-syllabic diagram to show organum at the octave, in a way that the Musica Enchiriadis' tetrachordal notation never could have.

My mistake, I meant c1000. Ps Odo predated Guido by about a generation, 25 years.

A question, and a possible correction.

Has the dating on "Odo" been revised? I had always thought he predated
Guido of Arezzo by a few years. (The online NGD2 entry on modal theory
still lists him as such, as of 10 min. ago...:)

Guido definitely uses the seven-letter notation system in both the _Regule
rithmice_ and the _Micrologus_, using an analogy to the 7 days of the week
that I believe is also used by Ps-Odo--no access just at the moment to check.
No idea if that analogy is original with Ps-Odo or was some sort of common
coinage--if anyone has info one way or another on that I'd love to hear it.:)
