  We analyze the concept of virtuosity as a collective attribute in music and
its relationship with the entropy based on an experiment that compares two sets
of digital signals played by composer-performer electric guitarists. Based on
an interdisciplinary approach related to the complex systems, we computed the
spectrum of signals, identified statistical distributions that best describe
them, and measured the Shannon entropy to establish their diversity. Findings
suggested that virtuosity might be related to a range of entropy values that
identify levels of diversity of the frequency components of audio signals.
Despite the presence of different values of entropy in the two sets of signals,
they are statistically similar. Therefore, entropy values can be interpreted as
levels of virtuosity in music.
