Cover song identification method and system

A computing device that facilitates cover song identification comprising:

• one or more processors;
• and
• a tangible, non-transitory computer-readable storage medium comprising instructions that, when executed by the one or more processors, cause the computing device to perform a set of operations comprising:
• deriving, from one or more harmonic pitch class profile (HPCP) features associated with target audio content, a major chord profile feature and a minor chord profile feature associated with the target audio content, wherein deriving the major chord profile feature and the minor chord profile feature associated with the target audio content comprises selecting HPCP features that correlate with twelve different major chords and twelve different minor chords, time aligning the selected HPCP features to a nearest bar line or measure based on an estimated tempo and beat associated with the target audio content, and normalizing the time aligned selected HPCP features, to emphasize a sequential structure of the target audio content with major and minor chords that are present in the target audio content;
• and
• determining, by machine learning logic, based on at least the major chord profile feature and the minor chord profile feature, a relatedness between the target audio content and at least one audio content item of a database, wherein the at least one content item is associated with cover song information.
