Best memory jogger...

The best sharps and flats reminder I've ever heard:

Father Christmas Gave Dad An Electric Blanket
Blanket Exploded And Dad Got Cold Feet

 

Father Christmas Goes Down And Eats Breakfast is how I learnt!

 

I use the Electric blanket version, but I also like:

Father Charles Goes Down And Ends Battle
Battle Ends And Down Goes Charles' Father

If you are one of those people who likes word patterns then the exact reverse that this gives means that one phrase can help you learn both sharps and flats.

 

One I like for remembering the #keys is:
God Descended And Every Body Farted, Cool!

 

sounds a bit fishy to me

 

Freddy Can Go Down And Eat Buns &

British European Airways Do Good Cheap Flights - now that shows my age!

 

I Learnt...
