Music is a vital part of life at Felsted Preparatory School. Both curricular and extra curricular music is available to pupils with many different music groups and clubs as well as one-to-one teaching. The Phillips Music centre provides facilities for these one-to-one lessons with three practice rooms and a percussion room.

The annual League Music Competition held in the Autumn Term allows pupils to show off their talents to the rest of the School. Each league has a junior and senior Individual performance, a junior and senior Group performance and an entire League performance. It is judged by an external adjudicator and causes great excitement and team spirit amongst the Leagues.
