  Music large-scale form, the structure of musical units ranging over several
bars, are studied using EEG measurements of 25 participants listened to the
first four minutes of a piece of electronic dance music (EDM). Grand-averages
of event-related potentials (ERPs) calculated for all electrodes show dynamics
in phase synchronization between different brain regions. Here local maxima of
the perceptual parameters correspond to strong synchronization, which culminate
at time points, where musical large-scale form boundaries were perceptually
expected. Significant differences between local maxima and minima were found,
using a Paired Samples t-test, showing global neural synchronization between
different brain regions most strongly in the gamma-band EEG frequency range.
Such synchronization increases before musical large-scale form boundaries, and
decreases afterwards, therefore representing musical large-scale form
perception.
