Music & Film By 1 min read

Quick answer

German composer Ludwig van Beethoven wrote the Moonlight Sonata in 1801. Its official title is Piano Sonata No. 14 in C-sharp minor, Op. 27 No. 2, marked “Quasi una fantasia” (“almost a fantasy”). The nickname “Moonlight” was given years after his death by a music critic who said the first movement reminded him of moonlight on a lake.

Key facts

Official title

Dedicated to
Countess Giulietta Guicciardi, his pupil

How it got its name

In 1832, five years after Beethoven died, German music critic and poet Ludwig Rellstab compared the first movement to moonlight shining on Lake Lucerne in Switzerland. The nickname stuck so firmly that most people know the piece only as the Moonlight Sonata. Beethoven himself never used it.

Three movements

MovementTempoCharacter
1stAdagio sostenuto (slow)Quiet, dreamy and sorrowful; the famous part
2ndAllegrettoLight and graceful; Franz Liszt called it “a flower between two abysses”
3rdPresto agitato (very fast)Stormy and dramatic, very difficult to play

Unusually, Beethoven put the slow movement first and saved the fastest for last, which is why he called it “almost a fantasy.”

The dedication

Beethoven dedicated the sonata to Countess Giulietta Guicciardi, a young pupil he was reportedly in love with. Her family’s social rank meant they could never marry.

Composing while going deaf

By 1801, Beethoven was already losing his hearing. A year later he wrote the Heiligenstadt Testament, a letter describing his despair. He went on to compose some of his greatest works, including the Ninth Symphony, while almost completely deaf.

Beethoven’s other famous works

  • Symphony No. 5, with its famous four-note opening
  • Symphony No. 9, whose “Ode to Joy” is the anthem of the European Union
  • Für Elise, a short piano piece
  • His only opera, Fidelio

Beethoven (1770–1827) was born in Bonn and spent most of his career in Vienna. For a much more recent composer, see who composed the Star Wars music.
