Music understanding from audio track and performance is a key problem and a challenge for many applications ranging from: automated music transcoding, music education, interactive performance, etc. The transcoding of polyphonic music is a one of the most complex and still open task to be solved in order to become a common tool for the above mentioned applications. Techniques suitable for monophonic transcoding have shown to be largely unsuitable for polyphonic cases. Recently, a range of

Several different approaches are based on techniques such as: pitch trajectory analysis, harmonic clustering, bispectral analysis, event tracking, nonnegative matrix factorization, hidden Markov model. The chapter will focus on analyzing the evolution of music understanding algorithms and models from monophonic to polyphonic, showing and comparing the solutions, while commenting them against commonly accepted assessment methods and formal metrics.
