A little 'byte' music: IU informatics prof fine tunes musical accompaniment
By Joe Stuteville
Mozart, mathematics and computers long have been an integral part of Christopher Raphael's life, and he has found a way to bring those three passions into harmony for musicians and music lovers.
Raphael, associate professor at the IU School of Informatics, has developed Music Plus One (MPO), a sophisticated computerized instrumental accompaniment program that responds in real time to a soloist's tempo changes and other expressive gestures, drawn from recorded past rehearsals from, say, a concerto or sonata. As the musician plays, the accompanying music is synthesized through an audio recording.
"MPO adds to a soloist's experience by providing a responsive and nuanced accompaniment rather than subtracting from it by imposing a rigid framework that stifles musical expression," said Raphael, who holds a doctorate in applied mathematics.
MPO makes advances on a long-time popular training record called Music Minus One (MMO) where a student plays a missing solo part with the recording supplying the instrumental accompaniment.
Raphael's current research, which has received funding from the National Science Foundation, synthesizes sound data from sampled audio recordings of accompaniments derived from MMO. Another focus of his uses polyphonic solo input, thus allowing a piano or several instruments to play the role of soloist.
"I believe these accompaniment systems will someday be as commonplace in the musician's toolbox as the metronome and tuner-but much more appreciated," said Raphael.
When he was 17, Raphael, an oboist, was the winner of the San Francisco Symphony Young Artist competition. He later performed with the Santa Cruz Symphony.
Informatics is an evolving field that explains the impact of information technology and develops new uses for it in areas such as health, science, the arts, education, business and industry.
