In the course of a 50-year period, Haydn composed some 80 string quartets, whose range and variety of structural invention rank second only to those of Beethoven. This fine new anthology consists of the six pieces known collectively as Op. 17: String Quartet in E Major, Op. 17, No. 1; String Quartet in F Major, Op. 17, No. 2; String Quartet in E-flat Major, Op. 17, No. 3, and three other pieces.
