Music 680: Special Topics in Music Theory - Electronics in Performance (Fall 2006) Class 10: November 13, 2006 spectralism as the conflation of timbre and harmony timbre as a set of frequencies, with the fundamental typically indicating the perceived pitch basics of spectral technique frequencies likely to create fusions harmonic series "stretched" harmonic series ring modulation frequency modulation (Murail's bell timbres) approximating these frequencies with pitch quarter-tone approximations typical, but also semitones or even wider approximations Fineberg's chart for transforming frequency to pitch influences leading up to spectral music Messaien, Scelsi, Ligeti, Stockhausen Tristan Murail Desintegrations (1982-83) for 17 instruments and tape highly sectionalized, and then process-oriented inside each section typically proceeding from fission to fusion, or vice versa or enacting some kind of gradual distortion process upon on an initial (or final) spectrum tape is used to "fill in" frequencies which are not convenient to the instrumental resources [which is to say, it sounds "empty" on its own terms, but highly integrated in context] low-tech method of creating the tape: using Yamaha FM synths as sinewave generators Jonathan Harvey Tombeau de Messaien (1994) for piano and tape with the tape serving as alternate tunings for the piano one just-intonation tuning for each chromatic pitch though often Harvey is using multiple tunings at the same time seeking clash rather than systemic purity Messaien as a proto-spectral composer: organ registrated and orchestrated harmony (and as the teacher of Murail and Grisey) Pd as a spectral sketchpad modeling and sonifying spectra locating and sonifying equal-tempered approximations to spectra frequency modulation as a major influence on Murail and Grisey preview of next week: Nono Omaggio a Gyšrgy Kurtag (scores on reserve) reminder: EAMC concert Thursday, November 16, 2006, 7:30 pm includes spectral music - Chris Bailey's Sand assignment 6: compose a brief work that engages with the issue of spectralism either spectra as pitch material, or pitches as spectral material (or both?) due in class December 4
