I didn’t realize Purchase didn’t offer music ed. I also looked up Binghamton (no music ed) and Stony Brook:
If you feel certain that you want to teach music on the pre-college level, you may want to consider an institution that offers a Bachelor of Music Education degree. However, Stony Brook prides itself on offering a rigorous music program that will prepare students for any graduate degree in music. Many of our students obtain the Bachelor of Arts in Music degree at Stony Brook and enter a master’s degree program to receive the Master of Music Education degree. Many are now teaching successfully in New York state.
Are you in the city? Aaron Copland in Queens has music ed:
Aaron Copland School of Music (cuny.edu)
as does Brooklyn College Music Education, B.Mus. | Brooklyn College (cuny.edu)
It seems that SUNY’s are the best option: Fredonia, Potsdam/Crane. It looks like Buffalo as well but that is farther away.
Mason Gross at Rutgers BM | Music at Mason Gross School of the Arts (rutgers.edu)
Temple Boyer, Hartt School in Hartford, Ithaca??
