A composer and artificial intelligence expert Eduardo Miranda, at the University of Plymouth is writing a piece of music for slime mould and traditional instruments. The piece will premiere next year. The idea started by using electrodes to measure the moulds electrical activity as it grew and feeding the signals into electronic sound generators. While working on this Miranda began to believe that the mould was intelligent and that perhaps there could be interaction with it so started to develop a feedback mechanism to turn audio signals into light, allowing the mould to ‘hear’ what its fellow musicians were playing.
