As the number of adults seeking to learn the piano increases, so too does the need for piano teachers to understand how to better facilitate their learning. Self-direction is an oft-cited requirement of adult learning, but one that is often absent from piano studios. This practitioner-based research investigates the role of the teacher in fostering and supporting self-direction, empowering adult piano students to take ownership of their learning. It offers pedagogical insights into the author's experiences within her own piano studio and details the practical application of theories and strategies offered within the fields of piano pedagogy and adult learning. This study finds that fostering self-direction is more complex than offering the balance between guidance and freedom that some experts suggest. It also requires strong student-teacher rapport, supporting and building students' self-efficacy and being willing to set aside expectations. This was made possible by implementing transformative pedagogical strategies, such as effective questioning, collaborative discussions and adapting the structure of lessons. While the author's journey is uniquely her own, the approaches used to engage adult students with their learning, and the use of reflective practice as professional development, may be of interest to other studio instrumental teachers.
