Abstract

Information rate (IR) was recently introduced as a novel measure of musical structure that quantifies prediction properties of musical signals. Formulated in information theoretic terms, it quantifies the rate of change of information in time series, and is related to capability of a system to perform information analysis of the data, such as actions involved in music listening. In this paper we extend IR measure to the case of MIDI sequences and perform a comparative analysis of audio signals (acoustic recordings) and symbolic representations (note, i.e. MIDI) of same musical piece. We show that in both cases IR detects similar types of structure, suggesting that IR might capture some inherent properties of musical signals.
