Finn is a piano teacher specialising in Baroque harpsichord repertoire. At Bard College, in Upstate New York, Finn studied piano with German Diez and harpsichord with Dr. Fred Hammond. During this period, he has given recitals as both an accompanist and soloist, including a performance with the American Symphony Orchestra under the baton of Leon Botstein.
Since arriving in Sydney in 2000, Finn has completed research at UNSW concerning musical aesthetics and psychophysics and continues to perform, compose and write about music. Lessons are centered around exam and recital preparation, and focus on theory, fingering, technique, interpretation, and memorization. Students perform works at the end of the year at a student recital held at the Conservatorium.
