Joni Mitchell once said, “I see music as fluid architecture.” The All Souls Episcopal Church in Stony Brook Village gives people an opportunity to revel in both at once.

The Saturdays at Six program offers classical music in concert the third Saturday of each month at 6 p.m.

On a recent Saturday the musicians were members of the Three Village Chamber Players, a group of Stony Brook graduate students who have been performing there over the past year.

“Our mission is to enrich our community through artistic excellence, providing musical performances of the highest caliber free to the public,” reads the statement on the group’s Facebook page.

For its part, the church shares the Players’ mission of serving the community.   

“The church’s doors are open every day so people can enter for prayer or reflection,” said Welcoming Chairman Daniel Kerr, while introducing the concert. Further, the church displays an active commitment to the arts with its Saturday programs that offer music, meditation and poetry on a regular basis, he said.

This program included Mozart’s String Quartet No. 19 in C major — nicknamed “Dissonance” — and, after an intermission, Ravel’s String Quartet in F major. Performers included the group’s director Natalie Kress, Anna Tsukervanik, Philip Carter (violins) and Alison Rowe (cello).

As an added treat, one of Kress’ violin students, five-year-old Leah Caravello, played a short piece.

The next Saturdays at Six concert will take place Nov. 19, when the members of the Anima Brass Quintet will perform.

Although the concert is free and open to all, a nonperishable food item donation is requested, and a “performer’s appreciation donation basket” is available, should people wish to contribute.
