Beethoven: String Quartet No. 10 in E-flat Major ("Harp"), Op. 74

The nickname "Harp" refers to the characteristic pizzicato sections in the Allegro of the first movement, where pairs of members of the quartet alternate notes in an arpeggio, reminiscent of the plucking of a harp. Like many nicknames for Beethoven's works, this was created by the publisher.
