What was studied

Ten professional drummers completed repetitive playing, pattern-based improvisation and free improvisation while EEG activity was recorded.

What it contributes

In 10 professional drummers, EEG-derived valence increased during pattern-based and free improvisation compared with baseline and was highest during freer improvisation; the study used solo tasks.

Where the evidence stops

EEG pilot with 10 professional drummers performing solo tasks; small sample and no ensemble interaction; not Oklahoma-specific.
