Have you ever wondered when the note mneumonics were first used? Does anyone have an idea?

Have you thought of any original ones?

Nope, they've never helped me much! I use numbers to remember things .
I know another one, though (I think everyone knows it): Great Big Dogs Fight Animals (for the lines in bass clef).

We've had thread similar to this before and they always seem degenerate into some unrepeatably rude mneumonics

Big Elephants Always Drink Gin, for the order of flat major keys.

Father Christmas Goes Down All Escalators Backwards, for the order of sharp major keys.

For the order of sharps I was always taught: Father Charles Goes Down And Ends Battle, and it is exactly the reverse for the order of flats - Battle Ends And Down Goes Charles' Father

All Cows Eat Ground-up-bits-of-other-animals-made-into-high-protein-feed .

lol

thats how i remember it!
