Casella Sinfonietta was created as an enhancement to the large ensemble offerings in the UNCG School of Music. Performing a range of works for 6 to 18 players, from the Renaissance period through world premieres, the ensemble functions on a professional model and performs one concert each semester. The personnel for each semester is determined by the repertoire, allowing the finest performers on wind, brass, string, percussion, and keyboard instruments the highest-level experience possible. Faculty and guest soloists and composers frequently collaborate with the ensemble.
