You may laugh out loud at Haydn’s “Joke” Quartet—Clara Schumann did when she heard it—and be dazzled by the “sweet, finely blended tone” (The Washington Post) of the Doric String Quartet. Haydn’s whimsical touches include an Austrian peasant dance—featuring an awkward country fiddler—and a finale that keeps you guessing about when it actually ends. There is nothing whimsical about Schubert’s grandly scaled final quartet: It’s a masterpiece of elegiac power and harmonic daring.
