Definition of Quantization (music)

Quantization (music) Definition from Encyclopedia Dictionaries & Glossaries
English Wikipedia - The Free Encyclopedia
In digital music processing technology, quantization is the process of transforming performed musical notes, which may have some imprecision due to expressive performance, to an underlying musical representation that eliminates this imprecision. The process results in notes being set on beats and on exact fractions of beats. The most difficult problem in quantization is determining which rhythmic fluctuations are imprecise or expressive (and should be removed by the quantization process) and which should be represented in the output score. For instance, a simple children's song should probably have very coarse quantization, resulting in few different outputted notes. On the other hand, quantizing a performance of a piano piece by Arnold Schoenberg, for instance, should result in many smaller notes, tuplets, etc.
