A data set of interbeat interval times is read into a music software synthesis program to become the basis of a " soundtrack " or auditory display. Here we present examples of the sonijkations, and discuss potential advantages in listening to, as opposed to viewing, heart rate variability data. This method treats the diagnosis of obstructive sleep apnea as(More)
During the second half of the twentieth century, algebraic methods have been increasingly recognised as powerful approaches to the formalisation of musical structures. This is evident in the American music-theoretical tradition as well as in the European formalised approach to music and musicology. We mention the mathematician and composer Milton Babbitt,(More)
—Monterey Mirror is an interactive stochastic music generator based on Markov models, genetic algorithms, and power-law metrics for music information retrieval. It combines the predictive power of Markov models with the innovative power of genetic algorithms, using power-law metrics for fitness evaluation. These metrics have been developed and refined in a(More)
The sonification metaphor is not limited to electronic sound synthesis and computer music, but can be applied to instrumental music as well. The relation of sonification to program and experimental music is discussed and works by Iannis Xenakis, Karlheinz Stockhausen, John Cage and Alvin Lucier are briefly introduced. The paper leads to a discussion of the(More)
This paper presents a new model for measuring similarity in a general Rhythm Space. Similarity is measured by establishing a comparison between subsequences of a given rhythm. We introduce the hierarchical subdivision of rhythm sequences in several levels, and compute a Distance Matrix for each level using the " block distance ". The information about the(More)
The paper aims at clarifying the pedagogical relevance of an algebraic-oriented perspective in the foundation of a structural and formalized approach in contemporary computational musicology. After briefly discussing the historical emergence of the concept of algebraic structure in systematic musicology, we present some pedagogical aspects of our MathTools(More)
1. Mathematics through Abstract Art sors immanis et inanis, rota tu volubilis 1.1. Abstractions. Both my parents were very deeply involved in the scene of Italian contemporary art, over the span of several decades. Both of them studied Architecture in the late 1950s and early 1960s at the Politecnico in Milan. My mother, who had been a student Ernesto(More)
The scope of this article is to present the diachronic value of Xenakis' technological thought in computer music research and creation of our days within a comparative and critical approach. On the one hand, we will refer to the main domains of Xenakis' contributions to Music Technology: the conquest of the computer as a tool for logical transformations of(More)
