This popular Ludwig van Beethoven composition for piano was composed in 1801 in Vienna, Austria. Moonlight Sonata became part of my life at age fourteen. Its full name is Piano Sonata No. 14 in C-Sharp Minor, Op. 27, No. 2 (Sonata Quasi Una Fantasia). When the first movement, Adagio sostenuto, entered my story this classical piece became one of my favorites in high school as I learned and memorized it to play in some recitals and as part of a program to be judged and critiqued.
