Abstract

The study of gestures in music performance provides valuable insights for instrumental learning. However, gestural vocabularies vary depending on the instrument being played, according to its postural and technical specificities. The goals of this study were twofold: first, to create a gesture categorization system for saxophone players, and second, to analyse their gestural behaviour across contrasting musical excerpts. A criteria-based observational analysis was conducted, considering the type and frequency of gestures identified in a database of 100 video and motion recordings. The categorization system, including 15 gesture types applicable to the case of saxophone playing, was further validated by 2 expert raters. A descriptive appendix is provided for the identification of each gesture type. Results revealed that: (1) knee and trunk flexion, feet elevation, mediolateral sway and flap were the most recurrent gestures among saxophone players; (2) energetic, fast-tempo excerpts led to higher movement frequency; and (3) impulsive gestures (head nods) were idiosyncratic of the excerpt containing repeated accentuated notes. These results present a definition of the gestural behaviour of saxophone players, which constitutes relevant knowledge for the development of future studies in the fields of injury prevention, body expression and historically informed performance.

基于视频的分类系统和萨克斯演奏手势频率分析

对音乐表演中手势的研究为乐器学习提供了宝贵的启示。然而，手势语汇因演奏乐器的姿势和技术特点而异。本研究的目标有两个：第一，为萨克斯管演奏者创建一个手势分类系统；第二，分析他们在对比音乐选段中的手势行为。研究采用了基于标准的观察分析方法，考虑了在 100 个视频和动作记录数据库中识别出的手势类型和频率。分类系统包括适用于萨克斯演奏的 15 种手势类型，并由两名专家评分员进一步验证。附录中对每种手势类型的识别进行了描述。结果显示(1) 膝关节和躯干屈曲、双脚抬高、内侧摇摆和扇动是萨克斯管演奏者中最常出现的手势；(2) 充满活力的快节奏选段导致较高的动作频率；(3) 冲动型手势（点头）是包含重复强调音符的选段的特质。这些结果为萨克斯管演奏者的手势行为提供了定义，为今后在预防损伤、肢体表达和有历史依据的演奏领域开展研究提供了相关知识。

期刊介绍： Psychology of Music and SEMPRE provide an international forum for researchers working in the fields of psychology of music and music education, to encourage the exchange of ideas and to disseminate research findings. Psychology of Music publishes peer-reviewed papers directed at increasing the scientific understanding of any psychological aspect of music. These include studies on listening, performing, creating, memorising, analysing, describing, learning, and teaching, as well as applied social, developmental, attitudinal and therapeutic studies. Special emphasis is placed on studies carried out in naturalistic settings, especially those which address the interface between music psychology and music education.
