Composers on Mathematical Music
Subtext 2137671


Recently, and I need not cite specific instances since a segment of the recent literature abounds with them, the scope of music apparently has been extended to include the interpretation in musical notation of arithmetical expressions. On this scale, at least, this is a new role for mathematics in the history of Western music: as a compositional prescriptive. Although the word “mathematics” has figured prominently in this history as both epithet and encomium, beyond the incidental notational use of number symbols, mathematics and music have been conjoined on the non-compositional level: in a Pythagorean, numerological, Quadrivium-oriented association, or quasi-analytically—as in such a familiar, characteristic case as the Esthétique musicale (1876) of Wronski and Durutte. The compositional invocations of “mathematics” which are current pose so many fundamental questions that only one of them will be even stated at this time. This centers around the apparent relationship of a mathematical expression and its musical representation inherent in these procedures, which parallels the relation between a formal theory and an interpretation of it. What, then, determines the choice of the mathematical expression? Usually, a formal theory is chosen or constructed in the light of an intended interpretation; what properties are possessed by an arithmetical progression, for example, which make it appropriate for interpretation as a metrical or ordinal pitch, or durational, or dynamic, or timbral, or density determinant? What data in the field of musical perception determine the rules of correlation? And what of the possible overpredictability and the assumed separability of the components of even the atomic musical event? All of these questions and others must be probed thoroughly before a decision can be even tentatively reached as to the extent to which such procedures enlarge the domain of music.
