Virtual drum: using computer vision for musical expression

Abstract

Musical instruments are transducers that convert forces applied by a human being into a c1~~s of .•.:l audio signals. With the availability of electronic devices that not only amplify the sounds generated, but also synthesize music when a small force sufficient to press a button is applied, the notion of 'force' is diminishing; instead, use of gestures to make music has gained more attention in recent research related to musical expression.
