Nathan Lam is a music theorist from Brisbane, Australia. His research examines the compositional use and perception of diatonic modes through different lens, including mathematical music theory, historical music theory, and solfège. His Ph.D. dissertation (2019 Indiana University) explores the reemergence of diatonic modes in Western art music ca. 1800–1950, and he has presented at regional, national, and international conferences, including Society of Music Theory meetings. Nathan’s 2017 paper “Relative diatonic modality” on la-minor solfège and English pastoral music won the Dorothy Payne Award. Other research interests of his include pentatonicism, canons, and musical symmetry. Putting theory into practice, Nathan also composes in his spare time. An upcoming CD album will include his solo and chamber works informed by his theoretical research.
