On June 26, Kevin Siegfried of the Boston Conservatory of Music leads The Portsmouth Singers in a program of his arrangements of Shaker music.

June 27 features a full day or workshops and a master class that is open to the public. Music ensembles will explore American chamber music under the direction of the Portland String Quartet. Tai Chi instructor and cellist Alex Wong will lead a session called “Selected Tai Chi Forms for String Players.” The master class begins at 3 p.m.

On June 28, guest oboe player Kathleen McNerney will join the quartet for Mozart’s Oboe Quartet in F Major, and composer Stephen Gryc will introduce his piece, Fantasy Variations on a Theme by Bela Bartok.
