Beethoven - Symphony No.7 in A major op.92 - II, Allegretto

Wikipedia - Symphony No. 7 (Beethoven)

At its première, Beethoven was noted as remarking that it was one of his best works. The second movement, Allegretto, was the most popular movement and had to be encored. The instant popularity of the Allegretto resulted in its frequent performance separate from the complete symphony.
