Special attention is given to aspects related to breathing, body awareness, and biomechanics, in order to provide a theoretical foundation for this approach and to propose pedagogical guidelines that foster a healthy, efficient, and expressive instrumental practice. A qualitative case-study design was adopted and applied to advanced-level guitarists. For data collection, various instruments were used: video observation (IR1), field notes (IR2), questionnaires (IR3), physiotherapy tests (IR4), body-schema drawings (IR5), and interviews (IR6). Data analysis was carried out through the development of descriptive matrices, triangulation of sources, and the application of ethical-rigor criteria typical of qualitative research.The findings show significant improvements in breath–posture integration—especially in the spine and cervical region—as well as reduced localized tension in the jaw and tongue. An increase in biomechanical efficiency in the forearms and fingers was also observed, accompanied by greater development of proprioception and musical expressivity. Inter-individual differences were identified, related to performers’ life trajectories and pre-existing movement patterns. The Cos-Art method emerges as a viable pedagogical framework for instrumental teaching by articulating the notion of bodily centers, axes, and “circles” in close relation to breathing as the structuring axis. An individualized pedagogy is recommended, with task designs oriented toward somatic attention, tonic regulation, and functional segmental organization. Likewise, future research should expand the sample and contrast the results with quantitative measures of technical performance and performers’ health.Keywords: Cos-Art; psychophysical education; classical guitar; breathing; body awareness.
