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.
