For their chamber music concert this year, the Festival’s resident string quartet takes on Brahms’s earnest, yet lovely, String Quartet No. 2. The piece is full of canons, or imitative melodies (a nod to Bach), and Hungarian themes (perhaps a nod to violinist Joseph Joachim, who played the premiere). Following, the Quartet will play Haydn’s Quartet Op. 76 No. 2, another formally serious but lively and gracious work, also with nods to Bach (note the canon in the 3rd movement) and Hungarian flourishes in the finale.
