Automatic Detection of Musical Repetition and Structure

Develop automatic methods to detect musical repetition and structural organization in music, enabling reliable identification of repeated phrases and sections in complete compositions.

Background

In their evaluation of musicality, the authors emphasize the importance of repetition and structure for assessing the coherence of generated music. They leverage ABC notation to perform a simple experiment that detects phrase-level repetition by checking the presence of repeat signs, but note that this approach is limited.

The authors explicitly state that automatic detection of repetition and structure remains unresolved, highlighting a gap in current methodologies for symbolic music analysis and evaluation. Addressing this problem would enable more robust quantitative assessments of musical structure in generated compositions.
