Synergismus is the premier violin-cello duo of Northern New Jersey. Its members, Millie and Randy Calistri-Yeh, have been playing together for 30 years in New York and New Jersey.

Synergismus offers an intriguing mix of classical, light classic, and popular music, many of which are original duet arrangements especially arranged for our group.

We can provide the perfect accompaniment to your wedding ceremony, reception, company event, fundraiser, or private party. We are happy to work with non-profit and community organizations to arrange a concert or recital.

Our home base includes Morris County (Morristown, East Hanover, Florham Park, Chatham, Madison, Morris Plains, Parsippany, Rockaway, etc), Essex County (Livingston, Millburn, Roseland, Caldwell, West Orange, etc), and Union County (Summit, Springfield, Berkeley Heights, Union, etc) in NJ.

Please contact us to book a performance.
