Abstract

Variability is inevitable in human movement and posture, including piano performance, although little research has been conducted in this area. The purpose of this study was to determine if, when comparing individuals to themselves, pianists demonstrate consistent postural angles within a task across multiple measurements and to ascertain if, between various tasks, there are discernible task-related postural patterns. Fifteen pianists participated in this study. Each pianist returned for a total of three measurement sessions. The tasks they were required to perform at each session were quiet sitting, raising their hands on and off the keyboard, playing an ascending and descending scale, sight reading, and playing a piece in three expressive conditions (i.e., deadpan, projected, exaggerated). The following postural angles were calculated based on motion capture data collected during the performance of these tasks: craniovertebral angle, head tilt, head-neck-trunk angle, trunk angle, thoracic angle, thoracolumbar angle, and lumbar angle. The within-person variability ratio across the three measurements was calculated for each angle and across all tasks. Task-related patterns in angles were examined by comparing the same postural angle across different tasks. Results showed that there is a considerable amount of within-person variability, but not enough to be inconsistent over time. Task-related patterns indicate that reading a musical score or playing at the extreme ends of the keyboard tend to involve leaning closer to the instrument. Implications for future studies, intervention studies in particular, include taking more than a single baseline measurement to provide a more accurate picture of an individual pianist's typical posture.
钢琴演奏中的体位变异
人类运动和姿势的可变性是不可避免的,包括钢琴演奏,尽管这方面的研究很少。这项研究的目的是确定在将个人与自己进行比较时,钢琴家是否在一项任务中通过多次测量表现出一致的姿势角度,并确定在各种任务之间是否存在可辨别的与任务相关的姿势模式。15位钢琴家参与了这项研究。每位钢琴家总共回来进行三次测量。他们在每次训练中需要完成的任务是安静地坐着,在键盘上和键盘下举手,演奏升降音阶,阅读,以及在三种表现条件下演奏一首曲子(即面无表情、投射、夸张)。根据在执行这些任务期间收集的运动捕捉数据计算以下姿势角度:颅骨角度、头部倾斜、头颈干角度、干角度、胸廓角度、胸腰椎角度和腰椎角度。针对每个角度和所有任务,计算三项测量的人内变异率。通过比较不同任务中相同的姿势角度来检查角度上的任务相关模式。结果表明,人与人之间存在相当大的可变性,但不足以随着时间的推移而不一致。与任务相关的模式表明,阅读乐谱或在键盘的末端演奏往往涉及向乐器倾斜。对未来研究的影响,尤其是干预研究,包括进行不止一次的基线测量,以更准确地了解钢琴家的典型姿势。
