Various musical notes set up sheet music in preparation for a performance of "The Blue Danube." As the music begins, however, it becomes apparent that a note is missing. The note (a red-faced "High Note") is revealed to be drunk, staggering out of the "Little Brown Jug" sheet music.
The irritated music-note conductor chases the intoxicated note, intending to put him back in his place so the waltz can properly continue. Throughout the pursuit, many objects are created from the simple musical notes: a dog, a slide, a clothes hanger, a lasso, horses, and more. Eventually, the rogue note is put back into place, but is again missing when the performance starts over. This time, though, the balance of the remaining music is also gone. The conductor discovers that all the notes have gone into the "Little Brown Jug" to get drunk. The original High Note, who is in Irving Berlin's "How Dry I Am," replaces the "I" with "We."
Animation historian Jerry Beck writes, "In today's world, where vintage cartoons are typically mistaken for children's fare, masterpieces like High Note set the record straight — with a healthy dose of classically adult booze humor."[4]
