Experimentally Investigating the Use of Score Features for Computational Models of Expressive Timing

In the expressive performance of music variation of tempo plays a major role in shaping and structuring the piece. We distinguish two aspects of tempo, the current tempo and the timing of individual notes with respect to the current tempo. Those two notions are influenced differently by the characteristics of the performed score. The relation between score and timing/tempo has many facets, one of which we examine more closely in the following. More precisely we provide experimental evidence for the hypothesis that timing is more aptly modeled with score characteristics from a small temporal score context, while tempo modeling profits from a bigger temporal score context.
