what was that mozart piece played in king of the hill

The Mozart piece in that King of the Hill moment is most likely “Eine kleine Nachtmusik” or another familiar Mozart violin cue used in the episode, but the source I found specifically confirms only that Connie is playing Mozart on violin in “The Bluegrass is Always Greener.”

What the episode tells us

• The episode summary confirms Connie is playing Mozart specifically while the guys are in the alley.

• It does not name the exact Mozart composition in the snippet I found.

Best match

• If you’re thinking of the recognizable, upbeat Mozart bit often associated with TV scenes, “Eine kleine Nachtmusik” is the most likely guess.
• But based on the available source here, that remains a best-fit identification , not a confirmed one.

Episode context

• The scene is from “The Bluegrass is Always Greener,” where Connie joins Hank’s bluegrass band and the violin/Mozart moment happens during the alley scenes.

TL;DR: The episode source confirms it was Mozart, but not the exact piece; “Eine kleine Nachtmusik” is the most plausible guess.
