What is it about?

On the basis of an approach based on set theory, polyphonic pieces of music can be directly compared with each other using multi-track MIDI files, by creating fingerprint diagrams and barcode sequences by transforming pitch sets and, derived from these, 'quasi-phylogenies'.

Why is it important?

With this approach, musicology may be able to perform systematic evolutionary analyses, comparable to a methodological approach that exists in evolutionary biology for more than three decades.


It will be the task of the musicology community to establish and agree on conventions about metadata and to elaborate the analytic process regarding the various parameters to be selected .
