Ludwig van Beethoven's Piano Sonata No.

7, sometimes nicknamed the Grand Sonata, was written in November 1796 and dedicated to his student Babette, the Countess Keglević.

[1][2] The sonata was composed during Beethoven's visit to the Keglevich Palace.

[3] Beethoven named it Great Sonata, because it was published alone, which was unusual for the time.

[4][1] A typical performance lasts about 28 minutes.
