In the beginning was not a word... it was a sound. Mother's heartbeat is the first sound a child hears inside the womb. This fact inspired me to imagine what a crowd sounds like. What can this rhythmic pattern be and how does it change. My tutor Oleg Makarov helped me to create a system that transforms a pulse into electronic beats in real time. The system consists of pulse sensors that send signals to a computer through Arduino to MaxMSP, and then a special code analyses them and starts playing kick drum loops on every peak of the heartbeat waveform. With this instrument I involve the audience in a collective improvisation, I create layered vocal loops over the generated rhythmical structure.
