Specifically, we introduce a system that supports users in exploring the high-dimensional space of musical chord sequences by parameterizing the variation among chord sequences in popular music. We provide a novel user interface that exposes these learned parameters as control axes, and we propose two automatic approaches for defining these axes. One approach is based on a novel clustering procedure, the other on principal components analysis. A user study compares our approaches for defining control axes both to each other and to an approach based on manually-assigned genre labels. Results show that our automatic methods for defining control axes provide a subjectively better user experience than axes based on manual genre labeling.}, publisher = {ACM}, url = {http://approjects.co.za/?big=en-us/research/publication/data-driven-exploration-musical-chord-sequences/}, pages = {227-236}, isbn = {978-1-60558-168-2}, edition = {IUI '09 Proceedings of the 14th international conference on Intelligent user interfaces}, }
