  The complexity of a system description is a function of the entropy of its
symbolic description. Prior to computing the entropy of the system description,
an observation scale has to be assumed. In natural language texts, typical
scales are binary, characters, and words. However, considering languages as
structures built around certain preconceived set of symbols, like words or
characters, is only a presumption. This study depicts the notion of the
Description Fundamental Scale as a set of symbols which serves to analyze the
essence a language structure. The concept of Fundamental Scale is tested using
English and MIDI music texts by means of an algorithm developed to search for a
set of symbols, which minimizes the system observed entropy, and therefore best
expresses the fundamental scale of the language employed. Test results show
that it is possible to find the Fundamental Scale of some languages. The
concept of Fundamental Scale, and the method for its determination, emerges as
an interesting tool to facilitate the study of languages and complex systems.
