SloMo study #2 was composed to explore the use of slow and microscopic body movements in electronic music performance, and the role of rhythmic visual cues and breathing in the perception of movement and time. To do so, it employs wearable sensors, variable-frequency stroboscopic lights, an electronic stethoscope, and a body-worn camera for face tracking. The performer's left hand very slowly draws an arc that begins with the left arm across the chest and ends when the arm is fully stretched outwards. The whole movement is performed in about 10 minutes, and marks the beginning and end of the piece. Breathing sounds, representing the inner tempo of the performer, are amplified. As the performer moves, the frequency of the stroboscopic light changes progressively from 1 to 30 Hz, reaching its maximum when the left arm is at the lowest point of the arc, approximately half-way through the piece. Variable-frequency stroboscopic light is used to alter the perception the audience has of the fluidity and speed of the performer's movements. In SloMo study #2, movements and rhythmic events entrain and interact at different timescales, sliding in and out of sync through the movements of the performer, affecting the perception of time.
