The Stearns Collection of Musical Instruments, held by the University of Michigan's School of Music, Theatre, and Dance in Ann Arbor, Michigan, consists of nearly 3000 historical and contemporary musical instruments from around the world.

[1] The basis of the Collection is a gift made to the university by pharmaceutical businessman Frederick Stearns in 1898.

[2] Known internationally as a unique research collection,[3] its holdings include the trumpet collection of Armando Ghitalla, former principal trumpet player of the Boston Symphony Orchestra and University of Michigan faculty member; a collection of violin bows from Jerry Tetewsky; as well as Robert Moog's first commercially produced Moog synthesizer from 1964[4] and the RCA theremin used during the WXYZ broadcasts of the Green Hornet from 1936 to 1952.

[6] In 1988, Professor James M. Borders published a catalog featuring the Collection's European and American wind and percussion instruments.

[7] The museum's collections include a number of forged or altered items, purchased by the founder from the notorious Italian instrument dealer Leopoldo Franciolini.
