The unit plan outlines an 8 lesson unit for a 3rd grade music class focusing on the piece "Viennese Musical Clock". Students will learn about the history of clocks, identify instruments in the piece, analyze its rondo form, compose their own pieces in rondo form, and create movements to represent different sections of the musical clock. Assessment includes having students identify instrument families in the piece, indicate form changes with coloring, and present their composed pieces. The unit aims to expose students to classical music and teach musical concepts.
