K.K. Sonata

"K.K. Sonata" is a K.K. Slider song that appeared in as a new addition to the game. It has a sad, 18th century mood, and is a classical composition that has a piano soloist throughout the whole song, without any other instruments accompanying the solitary pianist. Fittingly, the album cover depicts K.K. Slider parodying portraits of 17th-century German baroque composers: the cover's graphic design is clearly a reference to the long-standing tradition of uniform, yellow titles on the cover art of albums released on the classical record label Deutsche Grammophon.

The live version follows the correct structure for a sonata: exposition, development, and recapitulation, ending with a coda. The aircheck version forgoes this structure so that it can loop, only moving through exposition and development.

Annalise, Beardo, Miranda (in ), Muffy, Julia, Billy (both in ), Hans, Hippeux, Klaus, and Olivia (as of ) play this song if they own a stereo.
