Musical accompaniment algorithms for polyphonic performances
Presenter: Roberto Piassi Passos Bodo
In this talk we will present a paper by Joshua J. Bloch and Roger B. Dannenberg entitled "Real-Time Computer Accompaniment of Keyboard Performances" (ICMC 1985). In this paper a set of algorithms is developed to deal with real-time accompaniment of polyphonic performances.
We are in a scenario in which the computer listens to a musician's performance, compares the events of the input with the events of a score and, with a high correlation between them, infers a tempo and plays the appropriate accompaniment.
To handle with polyphonic instruments, the authors considered three design decisions: define the meaning of best association between performance and score, decide with confidence which point of the score the musician is and group disordered notes into compounds events.
