Automatic identification of musical chords
Daniel W. Martin · The Journal of the Acoustical Society of America · 1982
Various electronic and computer systems, which have been developed during the last fifteen years for identifying musical chords automatically, will be reviewed and compared. The purpose in most cases has been to facilitate easy-play, automatic musical accompaniment for musical beginners on electronic musical instruments. However the means used could also help provide low-cost instrumentation for real-time recording of new musical compositions, improvisations, and arrangements.
