This has got to be the most exhausting music joke I have ever heard…
A C, an E-flat, and a G go into a bar. The bartender says “Sorry, we don’t serve minors.”
So the E-flat leaves and the C and G have an open fifth between them. After a few drinks, the fifth is diminished, the G is out flat. An F comes in and tries to augment the situation, but is not sharp enough. A D comes in and heads for the bathroom saying “Excuse me, I’ll just be a second”.
Then an A comes in, but the bartender is not convinced that this relative of C is not a minor. The bartender notices a B-flat hiding at the end of the bar and exclaims “Get out now. You’re the seventh minor I’ve found in here tonight!”
The G was the one out flat? I guess he wasn’t so dominant after all. ba dum dum.
