| Abstract: | The increasing amount of music being stored in digital formats calls forincreasingly more creative methods for music information retrieval. One subsetof music retrieval methods relies on storing a melody in a pitch contourrepresentation. Most often, this contour information is generated either fromsymbolic format (MIDI) or from raw audio after a pitch transcription step. Inthis paper, we propose a method of extracting pitch contour information from musical audio without an intermediate transcription step by combining amusically-tuned constant Q transform with cross-correlation. When tested ona database of 520 monophonic music recordings, our method generates pitchcontours from raw audio data with up to 98 % accuracy. | ||
