Tri-M

Tri-M Music Honor Society, formerly known as Modern Music Masters, is an American high school and middle school music honor society. A program of the National Association for Music Education (NAfME), it is designed to recognize students for their academic and musical achievements and to provide leadership and service opportunities to young musicians. There are approximately 6,200 participating chapters in several countries, each of which is run by the students but supervised by an advisor or sponsor, usually a school teacher.

Tri-M was founded in 1936 by Alexander Harley and his wife, Frances. At the time, Alexander Harley was the band director and Music Department Chairman at Maine Township High School East in Park Ridge, Illinois. It has been a program of MENC: The National Association for Music Education since 1983. In 2011, the name MENC was changed to NAfME or the National Association for Music Education.
