Its goal is to unveil the “Harmonic Rhythm” of a musical piece, that is commonly understood as the rate at which the chords progress in a musical composition. The Shadow-Tonnetz keeps traces of the chords employed and helps displaying the “musical weight” of a specific chord and paths within a composition. It enables the spectator to better apprehend the key points and harmonic structure of a composition. In comparison with many current approaches, the visualization of harmonic progression including Speed and Weight is innovative and provides new horizons for the understanding of musical structures. Since these concepts work fine with the pieces that we have studied, we envision to use these principles for Tonal Center variations (see Spinnen-Tonnetz) [5]
