"Evaluating and Visualizing Effectiveness of Style Emulation in Musical Accompaniment"
by Ching-Hua Chuan and Elaine Chew

ABSTRACT: We propose general quantitative methods for evaluating and
visualizing the results of machine-generated style-specific
accompaniment. The evaluation of automated accompaniment systems, and
the degree to which they emulate a style, has been based primarily on
subjective opinion. To quantify style similarity between
machine-generated and original accompaniments, we propose two types of
measures: one based on transformations in the neo-Riemannian chord
space, and another based on the distribution ofmelody-chord
intervals. The first set of experiments demonstrate the methods on an
automatic style-specific accompaniment (ASSA) system. They test the
effect of training data choice on style emulation effectiveness, and
challenge the assumption that more data is better. The second set of
experiments compare the output of the ASSA system with those of a
rule-based system, and random chord generator. While the examples
focus primarily on machine emulation of Pop/Rock accompaniment, the
methods generalize to music of other genres.
