In her 2024 TSMT keynote address, Megan Lavengood challenged us to incorporate timbre lessons into the undergraduate music theory sequence. This poster responds by proposing a lesson module that engages this growing field of research. Following the scholarship, the lessons focus primarily on popular music with some suggestions for application to other styles (Blake 2012; Heidemann 2016; Lavengood 2020; Malawey 2020; Nobile 2022). Designed to fill 1-2 weeks of instructional time, these lessons do not require special equipment or instructor training. The module focuses on sound-source identification, from which students may move on to more advanced timbral topics such as spectrograms and studies in attack, sustain, decay, soundwaves, and overtones. The activity sequence follows Bloom's taxonomy of the cognitive domain (Bloom 1956). The poster includes complete assignment samples and links to playlists.
