This document summarizes research on the transition from piano student to piano teacher. It discusses the challenges piano teachers face in making this transition due to a lack of formal pedagogical training. While piano students study with a master teacher, they are not formally apprenticed in how to teach. The research explores how piano teachers learn to teach on their own and the resources and experiences that help prepare them. It also examines topics piano teachers feel are missing from their pedagogical training but would be useful to know.
