This video clip (2.2 MEG MPEG) shows cellist Yo-Yo Ma playing the hypercello at Tanglewood on August 14, 1991 to debut Tod Machover's hyperinstrument composition Begin Again Again...; it has since appeared in over a dozen different performances of Machover's music at various worldwide venues. The sensed parameters were used to trigger and modify synthesized sounds that accompanied the acoustic cello (turning it into a "hypercello"), as can be heard in the clip's soundtrack.
