RESUMO

The extraction of musical parameters from audio recordings enables a series of important applications in the field of musical analysis and classification. Harmony is a major issue on music structure, making the chord sequence of a musical piece an extremely relevant information on its analysis and a fundamental part of the musical graphic register. This work discusses the elements involved in musical harmony transcription as well as the mathematical and signal processing tools suitable to build an automatic method for the analysis and identification of chords, proposing a model capable of transcribing chord sequences from commercial audio recordings. The proposed system analyzes an audio signal and returns the symbols corresponding to the chords that best fit the signal.
