This article presents an excerpt from a completed master’s research study examining the professional aspirations of young students in the string section of the Musical Groups within Guri, a social music education and sociocultural inclusion project based in São Paulo, Brazil. Guri aims to promote musical education, collective music practice, and personal and social development for children and youth, providing access to structured training that many participants would otherwise not experience. This study focuses specifically on the benefits and challenges of collective string instrument teaching, highlighting students’ perspectives.The study employed a qualitative approach, with data collected through semi-structured interviews and documents provided by both Guri and the participating students. This methodological choice allowed for a nuanced understanding of the students’ experiences, capturing both musical and social dimensions of learning. The study’s theoretical framework drew upon works addressing youth studies, including Pais (1990, 2016), Bourdieu (1983), and Margulis and Urresti (1998), as well as research on collective music teaching by Cruvinel (2003), Ying (2012), Nascimento (2014), Paziani (2017), and Martins (2019). These sources offered insight into pedagogical structures and the broader social and cultural implications of collective music learning in a community-based setting.Results indicate that collective string teaching offers multiple benefits for students. Musically, the ensemble fosters motivation, encourages technical development, and provides early exposure to orchestral practice, which is significant for students aspiring to professional careers. Beyond musical skills, students reported enhanced social competencies, including empathy, collaboration, patience, and a stronger sense of belonging. Observing peers’ progress served as a reference for self-assessment, inspired personal improvement, and motivated students to overcome challenges.Participants also highlighted challenges associated with collective teaching. Teachers’ attention is divided, which can limit individualized support for students with higher professional aspirations. Additionally, the heterogeneity of skill levels within the group requires patience and adaptive teaching strategies. These findings underscore the importance of reflecting on pedagogical approaches that accommodate individual growth while maintaining the collective benefits of group learning.Overall, the study emphasizes that collective music teaching within Guri supports not only musical development but also socialization, critical reflection, resilience, and professional ambition. It demonstrates the transformative potential of social music projects and contributes to understanding how collective instrumental teaching can be effectively implemented to support both personal and professional development among young musicians in diverse contexts.
