WORKSHOP
PULSE AND PATTERNS
A workshop where participants will build small electro-mechanical solo drum
machines from single DC motors and small circuit boards. The workshop will
experiment with different kinds of sounding materials (metal pieces, stones,
springs, paper, etc), where the machines will oscillate freely and develop
their own individual sound quality. Once built the machines will be used
to explore fundamental musical structures.
