"Surely I've written better things," Beethoven said of his Piano Sonata No. 14 in C-sharp minor, Opus 27, No. 2. know best as his "Moonlight Sontata," and yet, this piece continues to be one that musicians return to over and over again. Originally composed for Beethoven's pupil, the countess Giulietta Guicciardi, the sonata perhaps captures some of the emotion between the two. Play this classic alone or for that special someone on Chromatik.
