One of the most frustrating and abstract concepts first-year music theory students encounter is voice-leading and four-voice part-writing. This lesson plan puts students in the driver’s seat as they discover voice-leading practices from literature. Initially students will discover voice-leading practices on their own in small groups by answering investigative questions, followed by confirming their findings with their peers. When they are ready to begin working in a four-voice or keyboard texture, students will have a model of guidelines for voice-leading from repertoire, not from a mysterious set of prescriptive rules.
