Daniel Müllensiefen, from the Department of Psychology, Goldsmiths College in London and Marc Pendzich, a Hamburg-based musicologist who did his dissertation on cover versions, have developed a software for determining if specific music is a plagiarism. They have tested their algorithms on a number of court decisions about musical plagiarism:
Müllensiefen, D., and Pendzich, M. (2009). Court decisions on music plagiarism and the predictive value of similarity algorithms. Musicae Scientiae, Discussion Forum 4B, 257-295.
The duo runs a company that sells expertise in the area of musical plagiarism.
