Music teachers instruct students in various musical genres and expression forms, such as classical, jazz, folk, pop, blues, rock, electronic etc. in a recreational context. They provide students with an overview of music history and repertoire, but primarily utilise a practice-based approach in their courses. In these courses, they assist students to experiment with different styles and techniques, in the musical instrument of their choice while encouraging them to develop their own style. They cast, direct, and produce musical performances, and coordinate the technical production.
