The difference between a choir and a choral society is as follows:

A choir is a music performance team, usually composed of professional musicians with a high level of singing. A choir usually consists of a conductor and accompanist as well as singers of different voices, and is characterized by a high degree of coordination and unity. Choirs usually perform in concert halls, theaters, etc., and sometimes participate in events such as competitions or music festivals.

The chorus club is a community group that includes people who are interested in participating in chorus. It includes not only members of the choir, but also students, adults, the elderly and other groups who are interested in chorus. Choir clubs usually rehearse and perform in rehearsal rooms, auditoriums and other places, and can also participate in various competitions and activities.

Therefore, there are differences between choirs and choral societies in terms of members, organizational forms, performance occasions, etc.
