Fragment 10.001 (PNM piece; Interlude 2 from Kraft)/ Wei-Han Wu, piano by Quarles published on 2018-10-06T18:16:44Z This piece first appeared in the journal Perspectives Of New Music, vol.56 no.1, 2018, in an article I co-wrote with mathematician and friend Daniel Sieburth, titled "All-trichordal Saturated M-chain Cycles". It implements two different types of all-trichordal pitch cycles, which composer Robert Morris first described in several articles in the 1980's . This piece is in three voices, and the cycles are projected as a result of the overall pitch event succession, rather than within each voice. Morris' first published all-trichord cycle is elided by a linkset of two pitches to an M-chain all-trichord cycle of my own design (the first one I found), an attempt to create a link between his music and mine, and an attempt to pay tribute to a former teacher. Here is a link to the article where the piece first appeared; I tried to include a comprehensive bibliography on pitch saturation, and intended it as a general tutorial in graph search and its application to pitch chains: https://www.jstor.org/stable/10.7757/persnewmusi.56.1.0171#metadata_info_tab_contents Thank you to Wei-Han Wu for the wonderful recording.
