Abstract
“1=f noise” describes the behavior of many naturally occurring
complex dynamical systems over time. Perhaps more surprising
than its ubiquity in nature is its prevalence in speech and especially
music. Current research suggests that aspects of the human
emotional response to music can be predicted using analysis based
upon 1=f distributions. Musical compositions in which the pitch
and duration of notes over time correspond to 1=f distributions
have been found to be more pleasant than non-1=f distributions.
The current research compares the sonification of a driven bead
pile to an experimentally contrived deviation. Preliminary results
suggest that the findings of pitch and duration may be extended to
timbre and spatialization. The benefits of continued research into
the application 1=f distributions in sonification for the auditory
display community are discussed.
