EDM Break Routines: grouping percept and action tendency

Electronic Dance Music (EDM) systematically influences dancers’ action tendencies through the modulation of timbre, amplitude, and rhythmic density. Tension and kineasthetic imagery are affected through “break routines”, consisting of breakdown (low-pass filtering to attenuate the primary pulse), build-up (progressive increases in energy, timbral brightness, and rhythmic density), and drop (the bassline and main beat is re-introduced, often with additional energy). The break routine operates as a continuous mechanism of tension and resolution, where dancers during the buildup are maintained in suspense for the anticipated release (the drop). For instance, the reduced pulse clarity at the breakdown, acoustically like being under a blanket, can be referred to by dancers as being “constricted”. As the buildup progresses, so does the tension and, eventually, the drop serves as a powerful resolution, with a clear action and pleasurable responses, reported in laboratory settings as well.



Notably, EDM production techniques achieve this effect through dynamic modulation of timbre, amplitude, and rhythmic density, whereas most models of tonal tension are based on discrete pitch relationships. We here present a model of musical tension in EDM departing from Gestalt grouping principles. Based on extracted acoustic parameters, the model formalizes violations of grouping principles of pitch proximity, timbral similarity, and temporal proximity, delineating a perceptual model of tension. The model was validated against continuous ratings of perceived tension and compared with motion data from published studies.
