K.K. Sonata is a K.K. Slider song that appeared in Animal Crossing: City Folk as a new addition to the game, and then returned in Animal Crossing: New Leaf. 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. Annalise, Beardo, Miranda (in Animal Crossing: New Leaf), Muffy, Julia and Billy (both in Animal Crossing: New Leaf - Welcome amiibo) play this song if they own a stereo.
