While listening to music, people, often
unwittingly, break down musical pieces into
constituent chunks such as verses and choruses.
Music segmentation studies have suggested that
some consensus regarding boundary perception
exists, despite individual differences. However,
neither the effects of experimental task (i.e. realtime
vs annotated segmentation), nor of musicianship
on boundary perception are clear. Our
study assesses musicianship effects and differences
between segmentation tasks. We conducted
a real-time task experiment to collect segmentations
by musicians and non-musicians from 9 musical
pieces; in a second experiment on non-realtime
segmentation, musicians indicated boundaries
and their strength for 6 examples. Kernel
density estimation was used to develop multiscale
segmentation models. Contrary to previous
research, no relationship was found between
boundary strength and boundary indication density,
although this might be contingent on stimuli
and other factors. In line with other studies,
no musicianship effects were found: our results showed high agreement between groups and similar
inter-subject correlations. Also consistent with
previous work, time scales between and 1 and 2
seconds were optimal for combining boundary indications.
In addition, we found effects of task on
number of indications, and a time lag between
tasks dependent on beat length. Also, the optimal
time scale for combining responses increased
when the pulse clarity or event density decreased.
Implications for future segmentation studies are
raised concerning the selection of time scales for
modelling boundary density, and time alignment
between models.

Interaction features for prediction of perceptual segmentation : Effects of musicianship and experimental task
Hartmann, Martin; Lartillot, Olivier; Toiviainen, Petri (Routledge, 2017)As music unfolds in time, structure is recognised and understood by listeners, regardless of their level of musical expertise. A number of studies have found spectral and tonal changes to quite successfully model boundaries ... -
Effects of musicianship and experimental task on perceptual segmentation
Hartmann, Martin; Lartillot, Oliver; Toiviainen, Petri (Royal Northern College of Music; European Society for the Cognitive Sciences of Music, 2015)The perceptual structure of music is a fundamental issue in music psychology that can be systematically addressed via computational models. This study estimated the contribution of spectral, rhythmic and tonal descriptors ... -

Multi-scale dynamics simulations of molecular polaritons : the effect of multiple cavity modes on polariton relaxation
Tichauer, Ruth H.; Feist, Johannes; Groenhof, Gerrit (AIP Publishing, 2021)Coupling molecules to the confined light modes of an optical cavity is showing great promise for manipulating chemical reactions. However, to fully exploit this principle and use cavities as a new tool for controlling ... -
