Cover Song Identification

Cover song identification refers to the task of recognizing different versions of a previously recorded musical work, even when these versions exhibit significant differences in timbre, tempo, structure, and fundamental aspects such as harmony and melody. This task is not only crucial for advancing computational musicology and music recommendation systems but also serves as a benchmark for other music similarity and retrieval algorithms. Chord analysis, melody extraction, and music similarity are closely related fields in music analysis that have all leveraged artificial intelligence techniques.
