Abstract

This paper illustrates an algorithm to generate a complex acoustic stimulus whose statistical properties are as close as possible to the non-stationary dynamics revealed by the current analysis of the electro-encephalogram activity of the human brain. Thus, the composition is driven by crucial events, namely renewal non-Poisson events with an inter-time distribution density (), which is an inverse power law with index , fitting the condition 1 ≤  ≤ 2. We find that the music composition is more attractive when we fill the time region between two consecutive crucial events so as to enhance the leading role of . In all cases the spectra markedly depart from the ideal 1/ condition, thereby suggesting a shift from the 1/ noise perspective of the pioneer work of Voss and Clark to the Zipf’s law perspective advocated by more recent work on music composition.
