Matriosity generates 12-tone matrices for use in serial music. You can enter a prime row as either letters or numbers and Matriosity will do the rest, generating the matrix as letters or numbers and also analyzing the prime forms of the dyads, trichords, tetrachords, and hexachords.
Matrices generated by Matriosity can be saved and printed.
IAN MCCOWAN Oh geez, I just two minutes ago turned in a 10-page paper on two of the biggies of twelve-tone and serialist music: Schoenberg and Boulez, and I come back to find this at the top of macupdate's software list.
That's surreal.
Anyway, unfortunately, this isn't a review of this software; I think serial music was a bit of an aesthetic misstep. If this program could play the rows and their various permutations, I might be tempted to check it out; any chance of adding that as a feature? (Version 1.0)
