K.K. Sonata

"K.K. Sonata" (, K.K.'s Sonata) is a K.K. Slider song that appeared in as a new addition to the game, and then returned in. 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 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 and Billy (both in ) play this song if they own a stereo.
