Though mainly active as a teacher, at such institutions as Brooklyn College, the College of Staten Island, the University of Western Ontario, and Wagner College, Arnold Rosner briefly served as assistant music director at WNYC from 1970 to 1972. Since 1983, he has taught at Kingsborough Community College.
The music of Arnold Rosner is couched formally in a neo-classical idion, but he freely admits melodic, harmonic, and contrapuntal methos of the modern school of composition. The Altoona Symphony Orchestra, the Colorado Philharmonic, the Denver Symphony Orchestra, the Jerusalem Symphony Orchestra, the New York Motet Choir, the Owensboro Symphony Orchestra, the Philharmonia Orchestra, the ensemble Pinotage, and other ensembles and orchestras have performed his music.
