In a time, when the hegemony of standardized practices contributes to the homogenization of human behaviors, investigating how to measure the level of complexity of our everyday rhythms may constitute a promising approach in human sciences. Inspired by the use of an algorithm to analyze the increasing occurence of repetitions in popular music lyrics from 1960's until today, this post explores the relevance of a mathematical tool to evaluate the evolution of the level of complexity inherent to the way we express ourselves.
