摘要: We present a study of coordination behavior in complex violin-bowing patterns involving simultaneous bow changes (reversal bowing direction) and string crossings (changing from one to another). Twenty-two violinists (8 advanced amateurs, 8 students with violin as major subject, 6 elite professionals) participated the experiment. investigated influence variety performance conditions (specific patterns, dynamic level, tempo, transposition) level expertise on (a.o., relative phase amplitude) stability. It was found that general highly consistent, characterized by systematic lead inclination over velocity about 15° (i.e., were consistently timed earlier than changes). Within similar conditions, high individual consistency found, whereas inter-individual agreement considerably less. Furthermore, influences stability which could be partly explained terms particular constraints. Concerning expertise, only subtle differences student professional groups (higher expertise) showing slightly higher amateur group (lower expertise). The observed current showed perceptual preferences reported an implying trajectories for important part emerge auditory-motor interaction.
