1 Introduction Automatic music transcription refers to extraction of a high level description from musical performance, for example in form of a music notation. Music notation can be viewed as a list of the pitch levels and corresponding timestamps. Ideally, one would like to recover a score directly from sound. Such a representation of the surface structure of music would be very useful in music information retrieval (Music-IR) and content description of musical material in large audio databases. However, when operating on sampled audio data from polyphonic acoustical signals, extraction of a score-like description is a very challenging auditory scene analysis task [13].
