Relationships Between Audio and Movement Features, and Perceived Emotions in Musical Performance
A core aspect of musical performance is communicating emotional and expressive intentions to the audience. Recognition of the musician's intentions is constructed from a combination of visual and auditory performance cues, as well as compositional features. The current study attempted to quantify these contributions by measuring relationships between ratings of perceived emotion, and motion and auditory performance features. A pianist and violinist with advanced degrees in music performance individually performed four short western tonal pieces. The musicians were tasked with performing the pieces while invoking different expressive intentions: sad, happy, angry, and as a control, deadpan. …
Musification of Accelerometry Data Towards Raising Awareness of Physical Activity
Previous research has shown that the temporal dynamics of human activity recorded by accelerometers share a similar structure with music. This opens the possibility to use musical sonification of accelerometry data to raise awareness of daily physical activity. In this study a method was developed for quantifying the daily structure of human activity using multigranular temporal segmentation, and applying it to produce musical sonifications. Two accelerometry recordings of physical activity were selected from a dataset, such that one shows more physical activity than the other. These data were segmented in different time-scales so that segmentation boundaries at a given time-scale have a co…
