Beethoven - Moonlight Sonata (FULL) - Piano Sonata No.14

The Piano Sonata No. 14 in C-sharp minor "Quasi una fantasia", Op. 27, No. 2, by Ludwig van Beethoven, is popularly known as the "Moonlight" Sonata. The work was completed in 1801 and dedicated to his pupil, 17-year-old Countess Giulietta Guicciardi, with whom Beethoven was, or had been in love.

The name "Moonlight" Sonata derives from an 1832 description of the first movement by poet Ludwig Rellstab, who compared it to moonlight shining upon Lake Lucerne.

Beethoven included the phrase "Quasi una fantasia" (Italian: Almost a fantasy) in the title partly because the sonata does not follow the traditional sonata pattern where the first movement is in regular sonata form, and where the three or four movements are arranged in a fast-slow-[fast]-fast sequence.

Ludwig van Beethoven (baptized 17 December 1770 - 26 March 1827) was a German composer and pianist. The crucial figure in the transition between the Classical and Romantic eras in Western art music, he remains one of the most famous and influential composers of all time.

Born in Bonn, then the capital of the Electorate of Cologne and part of the Holy Roman Empire, Beethoven moved to Vienna in his early 20s, studying with Joseph Haydn and quickly gaining a reputation as a virtuoso pianist.

His hearing began to deteriorate in the late 1790s, yet he continued to compose, conduct, and perform, even after becoming completely deaf.
