This is a sound performance about interactive instruments that take input from body movement and heart beat pulse, to amplify the sound expression. Sounds are triggered by physical activities and are modified by changes in biological data.

Orchestra is composed by following units: Heart rate detection by PPG or ECG. Accelerometer embedded into a weight lifting object. Pressure sensor positioned under a matress. And a control box with different sensors and switches to add interesting sounds. Kinect sensor is used as a live instrument to run synthesized melodies, by angle calculations of users moving around space. Heart rate is used to control a solenoid to hit a real drum. This will give the beat for the performance controlled inconsciously by your body. In order to make change speed of heart beat, it should be needed to do some aerobical working on stage, weight lifting, running around the place or some squats.
