In general, professional choirs pay their singers more than amateur choirs. However, the amount of money that a singer can earn from singing in a choir varies depending on the choir's reputation, location, and size. Professional choirs that perform in major cities or with well-known orchestras typically pay their singers more than amateur choirs that perform in small towns or with community orchestras.
If you are interested in singing in a choir, you should contact the choir director to find out if they are a professional or amateur choir and if they pay their singers. You should also ask about the choir's rehearsal schedule, performance schedule, and any other requirements that they may have for their singers.
