カール・ツェルニー
According to Carl Czerny, the second movement of the quartet occurred to Beethoven as he contemplated the starry sky and thought of the music of the spheres (Thayer, "Life of Beethoven"); it has a hymnlike quality reminiscent of a much later devotion, the "Heiliger Dankgesang" hymn to the Divine in the Quartet Op. 132.
