Explore the intersection of music and complexity science in this 38-minute lecture from the Santa Fe Institute's Complexity and the Structure of Music Working Group. Delve into the narrative structure of classical music across five centuries, examining concepts like the Arrow of Time, irreversibility, and directionality in musical composition. Discover how time series analysis techniques, including Multiple Scaling Detrended Fluctuation Analysis, reveal long and short-range correlations in musical structure. Investigate the relationship between pleasantness and nonlinear correlations in music, and learn about the Asymmetry Index for comparing original pieces with surrogate data. Gain insights into the universal features and evolutionary perspectives of music across cultures through this fascinating exploration of music theory and complex systems analysis.

Science-Music
Time Series Analysis: • Multiple Scaling Detrended Fluctuation Analysis, Long/Short Range Correlations, (Musical Structure)
Pleasantness is correlated to nonlinear correlations
The Arrow of Time Narrative
The concepts of irreversibility, directionality, and their musical implications have been evoked in music theory under multiple forms. For instance, temporal directionality has been established in terms of irreversiblerelations of "before" and "after"...
Comparison between original data and surrogate data (without nonlinear correlations)
