Watch High Note

"High Note (Looney Tunes)" (1960) is an American cartoon short made by Warner Bros. It has no dialogue, but plenty of music. In it, musical notes on some sheet music come to life, much to the surprise and annoyance of a conductor getting ready to perform. One of the notes is drunk and wanders off. The conductor chases it. During the chase, some of the other notes transform into things like a horse, a lasso and a slide.
