Ludwig van Beethoven's Piano Sonata No. 4, in E♭ major, Op. 7, sometimes nicknamed the Grand Sonata, is dedicated to his student Babette, the Countess Keglevics. This piano sonata was composed in Bratislava, in 1796, in November, during his visit of Keglevich Palace in Bratislava. Beethoven named it Great Sonata, because it was published alone, which was unusual for the time.
