The study and performance of ensemble repertoire can provide benefits at all levels of music study. Playing piano duos (two people at two pianos) is enjoyable for young students and can help maintain their interest in playing the piano. Furthermore, skills acquired in duo-piano playing, such as communication, coordination, and balance can not only be transferred to solo and/or duet performance, but can also develop a foundation for performing other types of chamber music, thus preparing young students to accompany other instrumentalists or vocalists or even a choir in the near future. This study provides a pedagogical guide that presents suggestions for teaching intermediate-level technical, musical skills, and collaborative skills through the study of selected intermediate-level piano duos from various musical periods.
