[A. Merriam] neglects to take sufficiently into account the possibilities of critical musical analysis as though from within the culture, be it by a … - Harold Powers

A tonal type is minimally identifiable by its three markers and thus objectively observable completely apart from its musical or cultural context; it is 'scientific,' it is 'etic.' 'Mode' conversely is all bound up in sixteenth-century musical culture, not as a living doctrine of the music of the church and a heritage fomr the Middle Ages but also as a musical construct being expirimented with by members of the culture, from both humanistic and traditional points of view; it is thoroughly 'emic' and requires study on its own terms....

'Objective' analysis is a tool, primarily useful for suggesting or confirming putative relationships between different musical styles....'Critical' analysis results not in a statistical measurement of style or proof of relationship but rather, ideally, in a formal model for a relatively independent and artistically controllable style within a culture, and should then be viable for accounting for individual manifestations of that style...

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."
