(English) With a cassette containing an original composition by Daniel Starr of Yale University. Second International Conference on Combinatorial Mathematics (New York, 1978), pp. 47--63, Ann. New York Acad. Sci., 319, New York Acad. Sci., New York, 1979. 81k:05023b 05B20 20K01 Bazelow, Alexander R.; Brickle, Frank A combinatorial problem in music theory---Babbitt's partition problem. II. (English) Ars Combin. 9 (1980), 289--306. Mathematical features in 12-tone musical composition have long been recognized and exploited, in particular by M. Babbitt. For a survey including references to Babbitt's writings, see, for example, Chapter I of an article by G. D. Halsey and the reviewer (Jahresber. Deutsch Math.-Verein. 80 (1978), no. 4, 151 - 207; MR 80g:20063). In the papers under review, the authors take up principally three problems posed by Babbitt that are of interest for musical composition. One of these is the problem of finding an algorithm for determining all m{times}m matrices with entries drawn from the set (1, 2, ... ,n) for which all rows and columns have the sum n. Here m and n are arbitrary positive integers. The authors point out in part II that this problem has been solved (albeit by a not strictly constructive argument) by R. P. Stanley (Duke Math. J. 43 (1976), no. 3, 511 - 531; MR 56 #2865). The second and third problems of Babbitt have to do with certain s{times}n matrices, the rows of which are the set of numbers (0, 1, ... , n - 1) in various specified orders, and how these matrices can be decomposed into blocks having certain specified properties. The results obtained are, by the nature of the problem, incomplete. Part I comes with an accoutrement unique in the reviewer's experience: a cassette on which a chromatic 12-tone scale, six interesting hexachords, and a composition by Daniel Starr (which the reviewer found very engaging) are recorded.
