James Mosher first began teaching horn lessons privately in high school, when his band director in Grosse Ile, Michigan asked him to mentor emerging middle school horn students. He quickly developed a passion for teaching, which led him to pursue a career both in horn performance and private horn instruction. He earned his B.M. degree in Music Education from Boston University, then went to Switzerland, receiving the Certificat d’Etudes from l’Institut de Hautes Etudes Musicales. Following a two year contract with the Orquestra do Estado de São Paulo, in Brazil, Jim moved to Germany to perform in orchestras in Darmstadt and Aachen, before returning to the U.S. on a scholarship at the Yale School of Music, where he completed the Masters Degree in Music.


Upon his return to Boston, Jim quickly established himself in the musical performing community, and as a private teacher, serving as horn instructor in public school systems of several communities, including Brockton, Duxbury, Marshfield and Milton. He went on to become the horn instructor at the Longy School of Music, Powers Music School, and Winchester Community School, where he also served as Chair of Brass, Winds and Percussion.


In 1999 Jim founded his own teaching studio, French Horn Studio Boston, employing the teaching methods and philosophy that he had developed over the years with wide success. He was invited to join the faculty of New England Conservatory Preparatory School in 2006, where he continues to teach horn and coach chamber music, including the Honors Brass Quintet. He became Chair of Brass and Winds of the School of Continuing Education at NEC in 2015, and has been a driving force for advancing the instrumental programs.


As a performer, Jim plays Principal Horn in regional orchestras in the greater Boston area, and is in high demand both as a chamber musician and soloist. He founded and directs the Brass Consortium, an ensemble that concertizes throughout New England. He is also active as a natural hornist, performing on historical instruments in leading early instrument ensembles in Boston and New York.
