In this paper we focus on the analysis of sound producing gestures in the musical domain. We investigate the behavior of intraoral pressure exerted by a trumpet performer in the production of single and concatenated notes. Investigation is carried out with functional data analysis techniques. Results show that different variation patterns occur for single note production, which depend on dynamic level, suggesting the hypothesis that two different motor control programs are available. Results from analysis on consecutive notes give evidence that the coarticulation between two gesture curves cannot be modelled by linear superposition, and that local coarticulation is affected by contiguous units.
