MUSIC SCORE ALIGNMENT AND COMPUTER ACCOMPANIMENT.

The article discusses machine systems that generate musical accompaniment that follows live human performances by relating musical sound to musical notation. The prevalence of computer-accessible music, including sampled audio files found on compact discs and the Internet, is contrasted by symbolic music representations, which lists notes with pitch, onset time, and duration, though both are difficult for current computer systems to understand. The article focuses on music score matching, which automatically generates music to accompany an existing arrangement.
