Auditions for membership in Harmonium take place in late August through early September of each year. Depending on the needs of the group, a very small number of auditions may be heard at other times. Specific dates will be posted on this page when they become available. Reservations are required and may be made through email to Dr. Anne Matlack, director@harmonium.org.

In general, there are an extremely limited number of openings for excellent singers with good sight reading skills. The 20-minute auditions are held at Grace Episcopal Church, Madison Avenue at Kings Road in Madison, New Jersey. Rehearsals are held Sunday evenings, from the first Sunday after Labor Day through the beginning of the following June at Grace Lutheran Church, 65 East Main Street in Mendham.

Harmonium presents three subscription concerts per season in the Morristown area, and also participates in other events such as First Night. Dr. Matlack’s programming provides ample opportunity for the professional, as well as the serious amateur. For music educators seeking continuing education credits, Harmonium Choral Society is a Registered New Jersey Professional Development Provider. Member singers looking for individual or small group experience may audition for solos within the programmed works or audition to join the select 20-voice Harmonium Chamber Singers. Other members who are available during the school day, evenings, or weekends, may volunteer to sing in the Harmonium Outreach Chorus, which performs assemblies in elementary and middle schools, and shows for libraries, retirement homes, etc.
