Abstract

We present a preliminary study of using the information theoretic concept of cross-entropy to measure musical contrast in a symbolic context, with a focus on melody. We measure cross-entropy using the Information Dynamics Of Music (IDyOM) framework. Whilst our long term aim is to understand the use of contrast in Sonata form, in this paper we take a more general perspective and look at a broad spread of Western art music of the common practice era. Our results suggest that cross-entropy has a useful role as an objective measure of contrast, but that a fuller picture will require more work.
