The workshop's mission is to give students, performers, and educators an opportunity to meet and share ideas, talents, and opinions about the world of trombone.
Soloists, educators, and students, as well as university and college trombone ensembles from around the world, attend the workshop annually.
Activities include concerts, master classes, recitals, lectures and clinics by the leading artists of the day.
The workshop annually features premier performances of new works and arrangements for tenor and bass trombone.
In 1978, John Marcellus, former principal trombonist with the National Symphony Orchestra, along with John Melick, former trombone instructor at Towson State University, founded the Eastern Trombone Workshop at Towson State University in Baltimore, Maryland.
