  This study analyzes the spectrum of audio signals related to the work of
"Pi\`eces de viole des Cinq Livres" based on the collaborative work between
Marin Marais and Jordi Savall for the underlying musical information. In
particular, we explore the identification of possible statistical signatures
related to this musical work. Based on the complex systems approach, we compute
the spectrum of audio signals, analyze and identify their best-fit statistical
distributions, and plot their relative frequencies using the scientific pitch
notation. Findings suggest that the collection of frequency components related
to the spectrum of each of the books that form this audio work show highly
skewed and associated statistical distributions. Therefore, the most frequent
statistical distribution that best describes the collection of these audio data
and may be associated with a singular statistical signature is the exponential.
