This document outlines an agenda for a music class that will teach students about two-part inventions. The class will include listening to a Bach invention, reviewing the features of inventions which consist of an exposition introducing a short motif or theme, a development section that changes and restates the theme, and a recapitulation that repeats the theme in the tonic key. Students will then craft and alter their own short two-note themes for a basic two-part invention, restating their theme in at least three ways and ending as they began. The goal is for students to understand the basic structure of two-part inventions by the end of the lesson.
