The authors performed a behavioral study of the complexity of left-hand finger movements in classical guitar playing. Six professional guitarists played movement sequences in a fixed tempo. Left-hand finger movements were recorded in 3 dimensions, and the guitar sound was recorded synchronously. Assuming that performers prefer to avoid extreme joint angles when moving, the authors hypothesized 3 complexity factors. The results showed differential effects of the complexity factors on the performance measures and on participants' judgments of complexity. The results demonstrated that keeping the joints in the middle of their range is an important principle in guitar playing, and players exploit the available tolerance in timing and placement of the left-hand fingers to control the acoustic output variability.
作者对古典吉他演奏中左手手指动作的复杂性进行了一项行为研究。六名专业吉他手以固定节奏演奏动作序列。左手手指动作在三个维度上进行记录，同时同步录制吉他声音。假设演奏者在移动时倾向于避免极端关节角度，作者提出了三个复杂性因素。结果表明，复杂性因素对演奏指标和参与者的复杂性判断有不同影响。结果表明，将关节保持在其活动范围的中间是吉他演奏中的一个重要原则，演奏者利用左手手指在时间和位置上的可用容差来控制声音输出的变化。
