Tipping Points, Pulse Elasticity and Tonal Tension: An Empirical Study on What Generates Tipping Points
This provides a first quantitative framework for understanding tipping points in music, which is incremental as it applies existing computational methods to a new musical phenomenon.
The study tackled the problem of quantitatively describing musical tipping points by analyzing timing and tonal tension in Chopin Mazurkas, finding that most tipping points identified by listeners could be explained by statistically significant timing deviations or changepoints in tension parameters.
Tipping points are moments of change that characterise crucial turning points in a piece of music. This study presents a first step towards quantitatively and systematically describing the musical properties of tipping points. Timing information and computationally-derived tonal tension values which correspond to dissonance, distance from key, and harmonic motion are compared to tipping points in Ashkenazy's recordings of six Chopin Mazurkas, as identified by 35 listeners. The analysis shows that all popular tipping points but one could be explained by statistically significant timing deviations or changepoints in at least one of the three tension parameters.
