Predictive Models for Music
Abstract: Modeling long-term dependencies in time series has proved
very difficult to achieve with traditional machine learning methods. This problem
occurs when considering music data. In this paper, we introduce predictive models for
melodies. We decompose melodic modeling into two subtasks. We first propose a rhythm
model based on the distributions of distances between subsequences. Then, we define a
generative model for melodies given chords and rhythms based on modeling sequences of
Narmour features. The rhythm model consistently outperforms a standard Hidden Markov
Model in terms of conditional prediction accuracy on two different music databases.
Using a similar evaluation procedure, the proposed melodic model consistently
outperforms an Input/Output Hidden Markov Model. Furthermore, these models are able to
generate realistic melodies given appropriate musical contexts.
