In this preliminary study, we tested the comprehension and the production of tonal events in a group of parkinsonian patients with and without pharmacological treatment in comparison with control subjects. Significant differences were found in the production task only: pitch, tonal range, and fundamental frequency variations in the parkinsonian group were reduced.
