Symmetry Model Based Key Finding

Document Thumbnail

In this paper we introduce a new key finding algorithm that is based on the symmetry model introduced by Gatzsche et al. in [1], [2], [11]. The algorithm consists of two parts: First the most probable diatonic pitch class set of the musical piece is recognized. Second using one of the subspaces of the symmetry model the mode of the piece is estimated. The algorithm is evaluated with 100 Beatles songs, 90 newer Pop&Rock songs and 252 classical pieces from the Naxos database. The results will be compared to the algorithms of Lerch [3], Zhu et al. [4] and an algorithm based on binary major and minor chord profiles. The new algorithm has the highest overall key finding MIREX’05 score of 82,9 %.
