Given my present belief in the much greater range of variability as to both order and kind of complexity in the world's musics versus the world's lan… - Harold Powers

Counterpoint texts tend to resemble one another in the underlying principles of voice-leading they espouse and in the kinds of orderings of rules they provide, but no one could accuse the harmony texts of, let us say, Heinrich Schenker and Hugo Riemann, or of Allen Irvine McHose and Walter Piston--or for that matter, of Arnold Schoenberg, Paul Hindemith, and Roger Sessions--of being mutually compatible, either in premise or in practice.

In applications of the music-as-language metaphor we should attend to diverse musical traditions in musical terms, including not only traditions of the music we study but also traditions of how we study music.

Rules of simultaneous ensemble constraint can't be assumed a priori to be the kinds of rules or rest on the same foundations as rules for constraint on succession. They may well be similar, but they may well not be similar also. It seems to me that ensemble constraints must first be understood in their own terms, within musical cultures individually and comparitively, looking to what appear to be basic principles in each in light of the others, I would call such a study "comparative counterpoint."
