James Arnold Hepokoski was born on 20 December 1946 in Duluth, Minnesota.^[1] He earned his master's degree and PhD in Music History from Harvard University, studying with David G. Hughes, John M. Ward, Oliver Strunk and Christoph Wolff, earning his doctorate in 1979 with a dissertation on Giuseppe Verdi's Falstaff.^[1] Since 1999 he has been Professor of Music at Yale University; earlier he taught at the University of Minnesota and at Oberlin College.^[2] In July 2017 he became the Henry L. and Lucy G.

He is best known for his writing on sonata form and its relation to the works of Ludwig van Beethoven and Jean Sibelius, as well as examinations of the symphony tradition and Verdi's late operas. Beginning in 1990, he and theorist Warren Darcy developed a new approach to sonata analysis known as Sonata Theory, culminating in the book Elements of Sonata Theory which makes a large-scale argument about the relation of genre to musical structure and choices, and which was the recipient of the Society for Music Theory's 2008 Wallace Berry Award.^[1][2] In 2020 he published a concise Sonata Theory Handbook.^[4]
