tonfeld, 2007, improvisation with Tape-heads

tonfeld is a monochrome surface area over which 87 audio tapes have been spanned. Notes from overtone structures of varying density, from simple sinus tones through to complex noise, have been recorded on tape. Two interpreters play with tape heads a concerto that was specially written for tonfeld.
