If you aren't aware that Connecticut College doesn't have summer school classes, you could be forgiven for wondering why all the June undergrads are wandering around the quads and leafy paths of the campus playing lutes or recorders or perhaps toting cello cases.

It's because they're not students.

Instead, it's time for the annual Connecticut Early Music Festival, headquartered as always at Conn, and the musicians and participants will be omnipresent for the next three weeks. Under the direction of artistic director Ian Watson, the fest will feature six concerts, all taking place in Evans Hall. The schedule launches Friday with a program of Bach Harpsichord Music, and joining Watson onstage will be Gregory Hayes and Grant Moss, and the concert starts at 7:30 p.m. in Evans Hall.

Here's the rest of the schedule, and all performances take place in Evans Hall:

5 p.m. Sunday — All Beethoven Program with Sonatas for violin and fortepiano and Trio for violin, cello and fortepiano; Watson, violinist Sudan Ogata and cellist Guy Fishman.

7:30 p.m. Friday — Acis and Galatea, G.F. Handel; Handel + Haydn Society of Boston.

5 p.m. Sun., June 17 — For Two Lutes: Virtuoso Music from Italy and England; lutenists Paul O'Dette and Ronn McFarlane.

7:40 p.m.  Fri., June 22 — J.S. Bach: Music for cello da spalla, violin, cello and harpsichord; Watson, Fishman and multi-instrumentalist Zachary Carrettin.
