Group piano is the study of how to play the piano in a group setting. This contrasts with the more common individual/private lesson. Group piano originated at the beginning of the nineteenth century, and continues to be a widely-used method of piano instruction. Group lesson formats include master classes, university classes, and pre-college music lessons. These classes typically have between 3 and 16 students. Benefits of the group lesson format include the development of independent learning, ensemble playing, critical listening skills, and exposure to a wide range of repertoire. Group piano instruction may require more space and equipment, increased preparation per class, and more attention to scheduling and group interaction than when teaching individual/private lessons.
