| Outline of Final Research Achievements |
We have established a statistical framework that can jointly infer musical notes and syntactic structures from musical audio signals using a hierarchical Bayesian model based on integration of language and acoustic models. We tackled automatic music transcription for piano signals, musical note estimation for singing F0 trajectories, rhythm transcription for MIDI performances, automatic drum and guitar transcription for popular music audio signals. We applied these methods to assisting a user to sing a song and play a musical instrument. In addition, we developed an interactive music composition system based on a hierarchical Bayesian model of chords and melodies.
