"This volume, likely to become a standard reference work, describes an extraordinary number of approaches to the representation of musical information for purposes of computer processing. It is a considerable achievement, for it sorts and orders work in a confusing and sometimes embattled field, analyzing each encoding method in logical sequence and in light of the specific purposes for which it was designed." -- Raymond Erickson, Dean of Arts and Humanities, Queens College, CUNY; author of DARMS: A Reference Manual The establishment of the Musical Instrument Digital Interface (MIDI) in the late 1980s allowed hobbyists and musicians to experiment with sound control in ways that previously had been possible only in research studios. MIDI is nowthe most prevalent representation of music, but what it represents is based on hardware control protocols for sound synthesis. Programs that support sound input for graphics output necessarily span a gamut of representational categories. What...
