Abstract

This thesis presents a computer programme which allows users to provide vocalists with active musical accompaniment. In this case, the computer would stand in for various instruments, which would allow the soloist to sing without being accompanied by instrumentalists. The thesis has two goals. The first goal is to discover at which point in a given piece the singer is located, and the second goal is to create and play an accompanying musical score which will match the soloist’s piece. Results were obtained by using a hidden Markov model, analysing the signal, an algorithm used to search for the most probable state in the chain and mechanisms for ensuring a successful musical accompaniment. By testing this programme both goals were reached, since the programme was able to successfully determine the position of the singer, as well as successfully providing an active accompaniment, the score of which matched the score of the singer.
