Belmont has a large music program, and a variety of musical ensembles exist on the campus. There are currently 15 vocal ensembles and 23 instrumental ensembles. In addition, there are three student-run a cappella groups: The Beltones (mixed ensemble), Prismatics (mixed), and Pitchmen (TTBB). All three a cappella groups compete in the International Championship of Collegiate A Cappella (ICCA) regularly. The Beltones have advanced to ICCA finals three times and placed 4th at the event in 2014. The Pitchmen qualified for ICCA finals in 2020 but the event was cancelled due to the COVID-19 pandemic. In 2020, The A Cappella Archive ranked The Beltones at #8 amongst all ICCA-competing groups since 1996. Belmont is home to two Greek-lettered music fraternities, Sigma Alpha Iota and Phi Mu Alpha Sinfonia, as well as a chapter for the national theatre fraternity, Alpha Psi Omega.
