To know Beethoven is to know his most familiar sonata, the Piano Sonata No. 14 in C sharp minor, Quasi Una Fantasia, Opus 27, No. 2, composed in 1802, popularly known as "Moonlight Sonata." Although it being a great misfortune and aggravation, Beethoven's greatest work was accomplished after he had become deaf. His genius and geniality as an artist and his noble generosity won the hearts of the music lovers and caused them to condone his freaks. His entire life, of course, was confined to music as an orchestra leader, pianist and composer, and his compositions are without question the finest and greatest. He is still recognized as the greatest composer of instrumental music of all times, and even in vocal music his "Fidelio" and "Missa Solemnis" are creations of unique power. His works comprise 138 opus-numbers and about 70 unnumbered compositions.
