Music 680: Electronics in Performance Fall 2004 Lecture 8: November 8, 2004 assignment (due November 22, 2004) create a computer "improviser" using Pd that either responds to input (audio, MIDI) or generates directed structures (phrases, larger formal units) on command David Tudor: Pulsers, etc. composition as instrument-building improvisation: exploration vs. recycling John Cage / Electronic Music for Piano (1964) for piano or pianos and electronics score opposite tendencies from Stockhausen: informality, randomness (but not necessarily freedom) derived from previous Music for Piano series (1960) also referring to a variety of other works (Cartridge Music, Variations, Atlas Eclipticalis) evocative of the shared culture between Cage and Tudor much like Bussotti's Five Pieces for David Tudor [sidebar on David Tudor: from avant-garde piano to live electronic performance] does the piece require a performance of Music for Piano or is it improvisation? realization concepts freedom = ethical responsibility starting from the premise of Tudor as much as Cage feedback systems idiosyncratic / "broken" instruments as disruptive to improvisation habits / tendencies notion of "points" vs. lines (piano resonances, sustaining feedback tones) realization development a process of rehearsal, testing, and development [rapid development capabilities of Pd] seeking ways to integrate piano and feedback leads to more direct forms of piano processing ring modulation, resonator as ways to impose glissando on piano tones distortion layer becomes amplification layer serendipities interruptions derived from improvisation with audio switching spatialization from a separate project increasing number of controls and automations over time env~, fiddle,~, and bonk~
