Background: Posture, a multidimensional construct with historical, educational, sociocultural, behavioural, and health dimensions, is relevant to musicians’ occupational health, music education, and performance science. ‘Poor’ posture is often associated with musculoskeletal disorders or performance-related pain. However, a systematic review by Rousseau et al. (2023) found little clear evidence linking posture and pain, highlighting inconsistencies in definitions of optimal posture and criteria for postural analysis. Similarly, Shoebridge et al. (2017) proposed a broader interdisciplinary definition, considering cognitive, emotional, physical, and contextual factors. Yet, posture is still often described through static anatomical positions rather than movement quality or integration with musicianship.There is a need to explore and integrate different disciplinary understandings and applications of musicians’ ‘posture’ to improve outcomes, consistency, and quality of interdisciplinary research on musicians’ playing posture. Importantly, this has implications for improving postural strategies in music teaching.Aim: The aim is to explore how musicians’ ‘posture’ is understood, defined, and applied across musicians’ health, music education, and music performance research domains. Considering the breadth of the topic, the heterogeneity of the literature, a need to include a variety of study designs and publication types, and the purpose of clarifying key concepts, conducting a scoping review is therefore the appropriate method.Methods: This scoping review protocol was developed according to the JBI Manual for Evidence Synthesis guidelines and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist (Peters et al., 2022; Tricco et al., 2018). Following the PCC framework (Participants, Concept, Context), the included studies focussed on instrumentalists, described posture while playing, and encompassed all musical styles, genres, and levels of playing, in any setting. After removing duplicates, studies were screened independently on their title and abstracts first, then on the full text. Key characteristics extracted from the final included studies will be presented in tabular form, accompanied by a narrative summary.Results: Conducted from January-October 2025, the review will analyse: (1) definitions of playing posture, (2) posture and performance, (3) posture and health, (4) music teaching strategies, (5) “optimal” or “impaired” posture, and (6) clinical strategies. This presentation will focus on the strategies in music teaching.Conclusion: This scoping review is currently underway and the analysis and discussion will be completed by December 2025. The final study results and conclusions will be available to be presented in July 2026.
