Three Pieces Derived From a Bowed Metal Plate

They Ripped my Metal Heart Apart is a composition for bowed metal plate. The plate was held in a vise that was clamped to a work bench and three recordings were made each with a different clamping point of the plate. The sound was recorded via piezo pickup on bench and microphone in room. Post processing consisted of delay, reverb and panning with slight compression of the master.


The Space Between the Atoms for bowed gamelan in harmonic series / subharmonic series tuning using pitches derived from the original metal plate performance. Sonar X3 was used to extract the pitches and convert them to midi. The extracted pitches were transposed down by an octave. Significant “JI Growl” occurs through out the piece.


A Strange Orchestra is a trans-tuned 6 edo version of the original metal plate performance using melodyne single track to process the recording. At about 3 minutes in the sound becomes (to my ears) orchestral and far removed from the harshness of the original bowed metal plate performance.
