This study aimed to document the characteristics of accurate pitch performance in skilled cellists (intermediate-professional skill levels). Specifically, we examined the control principles underlying alternating shifting movements between notes, contributions of different sensory systems, serial movement strategies used by skilled cellists and the impact of removing sensory inputs on the serial movement strategies. Results showed that position variability stayed constant with increased movement velocity and distance; a feedforward control strategy was used in the primary movement phase; after initial landing auditory input was then used to achieve the desired pitch (error corrections); however, the pitch/position errors detected based on auditory information were corrected within the note but quickly ignored in future movements.

520 $a This study aimed to document the characteristics of accurate pitch performance in skilled cellists (intermediate-professional skill levels). Specifically, we examined the control principles underlying alternating shifting movements between notes, contributions of different sensory systems, serial movement strategies used by skilled cellists and the impact of removing sensory inputs on the serial movement strategies. Results showed that position variability stayed constant with increased movement velocity and distance; a feedforward control strategy was used in the primary movement phase; after initial landing auditory input was then used to achieve the desired pitch (error corrections); however, the pitch/position errors detected based on auditory information were corrected within the note but quickly ignored in future movements.
520 $a Cellists generally used location information (78%) rather than distance cues (11%) in the control of shifting movements. Cutaneous feedback from the thumb when it encountered the body-neck junction, a physical landmark of the cello body geometry enabled faster movement velocity (p<0.001) and lower position variability (p=0.01) of the neighboring note (E). It was also found that when vision was available performers attempted to use an ineffective strategy in which the last landing position was remembered and reproduced. When proprioceptive information was the only sensory input available, variability and accuracy of the initial landing position were the same as when auditory input was present, indicating that proprioceptive control is extremely accurate and stable for the initial programming of movement in these musicians.
520 $a These findings suggest that skilled cellists possess an extraordinary ability to maintain performance level across a variety of conditions. This may be due to long-term over-training, producing a stable platform for executing movements between loci governed by location programming. In addition, cellists with higher perceptual ability and performance proficiency were found to rely more on auditory input whereas less experienced cellists benefited more from vision; increased perceptual abilities and performance proficiency were associated with increased pitch accuracy but not reduced variability. This suggests that pitch accuracy was facilitated by increased perceptual ability, whereas movement variability (initial landing variability) was constrained by the capacity of the motor system, which is highly fine-tuned and different than that of non-musicians.
