Music Class
A young child returned from his first music lesson on the tuba.
"How did it go?" asked his father.
"Great," said the child. "I learned how to play a ‘C’."
The next week the child took another lesson and his father asked about the lesson.
"Terrific," said the child. "I learned how to play a ‘G’."
The following week the child didn’t come home.
The father was frantic with worry, till the child came home at 2:00 AM.
"Where in hell have you been?!" screamed the father…
"Out gigging," answered the son.

Not quite two notes, but close. Maybe this was after the third lesson, and of course the lead player was more advanced... maybe 5 lessons.
Lol - a few notes and a nice rhythm: the result is quite good and very cheerful.
