Musicologist Lewis Lockwood stated that his body of work "substantially extends current knowledge of the music history of the Italian Renaissance.
He received BMus and MMus degrees from Boston University, where his teachers included Karl Geiringer and Gardner Read.
At Harvard University he studied with Nino Pirrotta, A. Tillman Merritt, Randall Thompson and Walter Piston, receiving his MA in 1955 and PhD in 1960.
His writing for scholarly journals covered a wide variety of topics ranging from individual composers (i.e., Gagliamo, Isaac, Pisano[9]) to the musical activity in specific institutions (i.e., Cathedral of Santa Maria del Fiore).
With Howard Mayer Brown and Jesse A. Owens he edited the series Renaissance Music in Facsimile, and with Gilbert Reaney the journal Musica Disciplina.
