Fugue analysis

We present here a computational analysis of fugues, trying to automatically analyze their structure. You can switch between a reference analysis and the output of our method. Click on the link below each diagram to access an interactive version of these analysis, with scores. For more information, and discussion on this method and its results, please see the fugues main page and the bibliographical references. Music21 is used to generate these visualisations.
