tDCS and Musical Performance in Young Orchestra Musicians

The goal of this clinical trial is to learn if transcranial direct current stimulation (tDCS) can improve the technical, expressive, and stage aspects of musical performance in young orchestra musicians aged 18 to 30 years. The main questions it aims to answer are: * Does active tDCS improve musical performance compared to sham stimulation? * Does active tDCS reduce music performance anxiety and increase musical self-efficacy? Researchers will compare the active tDCS group to the sham stimulation group to see if active stimulation has positive effects on musical performance and psychological factors. Participants will: * Receive either active or sham tDCS stimulation * Perform a musical piece before and after stimulation * Complete questionnaires about anxiety and musical self-confidence
