. : back Liquidus . : for percussion and 2 computers : . : . mp3 . . : : photos Liquidus (2004) was conceived out of an aural motivation, the bending of metal like water. This work is an approach to computer music where reliance on the source signal, the acoustic instrument, by the computer and the interaction between the two, persuades the composition. This piece is produced entirely using the incoming sounds in real time, an approach that answers several problems related to expressiveness in electronic music. The computer generates material that responds to the nuances in articulations created by the performer on stage at every performance. The sound of the new instrument relies on the spectral makeup of the performers instrument to create the voice(s) of the piece. This signal dependency approach to the computer is intended to fuse the characteristics of the acoustic into the electroacoustic. Composition of the piece also leaned on the timbres of the live instrument. Intervallic relationships were derived from the spectrum of percussion instruments such as the opening crotales and used as the pitch content for much of the piece creating scalar and harmonic patterns that include quarter tones. These patterns of extended tunings are used to bend the signal by these ratios or to be used at times by the computer as sets from which to derive pitches. The result is a symbiotic instrument created between the percussion and the computer capable of refracting and isolating itself, a meta instrument controlled by one performer. Liquidus was composed and developed at the Institute for Sonology in The Hague and is dedicated to Diego Espinosa and Juan Parra. past performances CINCH Festival The Electronic Hammer Dec 2nd 2006 Gaudeamus Live EA Festival The Electronic Hammer Nov 24th 2006 Musikhochschule Holger Stenschke Jan 23rd 2006 NWEAMO The Electronic Hammer Oct 7th 2005 The Electronic Hammer NA Tour The Electronic Hammer Oct 4th 2005 Visiones Sonoras The Electronic Hammer Sep 21st 2005 De Kaas Toer The Electronic Hammer Oct 17th 2004 De Kaas Toer - Rumor Festival The Electronic Hammer Oct 16th 2004 De Kaas Toer - Locaal 01 The Electronic Hammer Oct 15th 2004 Interactivity Festival The Electronic Hammer May 30th 2004 BBC Radio 3 - Hear and Now Radio Broadcast The Electronic Hammer May 29th 2004 Sonology The Electronic Hammer May 13th 2004 SARC Inaguration Festival The Electronic Hammer Apr 28th 2004 The Gulf Tour - Aural Tick Festival The Electronic Hammer Apr 4th 2004 The Gulf Tour The Electronic Hammer Mar 28th 2004 The Gulf Tour The Electronic Hammer Mar 27th 2004 The Gulf Tour - Primavera en la Havana The Electronic Hammer Mar 16th 2004      Dec 6th 08  Symposium zu Körpergedächtnissen in Medien  seismic body memory  Freiburg U - Freiburg- D    Dec 7th 08  NVL  Idoru in Metals  Maastricht - NL    Jan 26th 09  Hammer Concert  Izumi  U of East Anglia - Norwich - UK
