The aim of this paper is to demonstrate the effect of L-Dopa treatment on the production of musical scale by Parkinsonian patients. In this preliminary study, we tested the capacity of the patients to vary the fundamental frequency of their voice as well as to control rise in frequency. Our hypothesis is that, in such a task, speech production should be phonetically affected for parkinsonian patients and improved by L-Dopa treatment. We also hypothesize that musical scale production would be an indicator of the subjects' capacity to produce intonation schemas according to a given instruction. If that is correct subject evidencing difficulties in ascending the scale would similarly have problems in handling adequately intonation patterns in language production (e.g. assertions, questions, etc.).
