Statistical Performance Model with Explicit Voice Structure and Symbolic Music Alignment

Ort: Room JKU S3-055 in Science Park 3

Zusammenfassung

The central problem in symbolic music alignment (a task of matching musical notes in performance MIDI files to the corresponding notes in the musical score) is how to deal with the varieties in human performances (e.g. tempo changes, performance errors, ornaments, repeats and skips, etc.). To solve the problem, the approach of applying generative statistical models of music performance is discussed. In particular, to deal with possible asynchrony between two hands in piano performances, the merged-output hidden Markov model is proposed as a model that explicitly incorporates the multiple-voice structure of polyphonic music. As applications, automatic music accompaniment and an alignment system are demonstrated.
