Your best mnemonic?

It was all very confusing.

Technically, there are no separate colours of the rainbow. A rainbow is a gradual spectrum of wavelength changes that are subjectively perceived as different colours by our sensory systems but only for convenience. Are red and orange separate colours? Where on the visible light spectrum does that separation occur? How do you know everyone else sees the sane two colours at the same point of separation?

For the open strings on my violin: Good Dogs Always Eat

And for my cello: Cats Go Down Alleys

I can't get the cranial nerves one in my head, but use the "some lovers..." one loads. There's a "sexy Lucy..." one that I can never remember and is a bit naughtier!

Another one from my junior school violin playing days is "Elephants Are Dark Grey" (the strings)

I was taught to spell Because as Birds Eat Crumbs After Uncle Stops Eating - even now I find my self repeating it when ever I have to spell it.

I still repeat in my head "O U Lovely Darling" whenever I write could/would/should

We weren't taught all that many at school, really, certainly not for spellings etc. We used

Never East Shredded Wheat

Every Good Boy Deserves Football and FACE for the 'spaces'

and the trig

Silly Old Harry

Caught A Herring

Trawling Off Afghanistan

(and it was incredibly useful when I chose a maths module as part of my OU degree recently! ? )

Didn't know the planets one, so have spent the last 5 minutes trying to memorise it - every day's a school day!

I know this is not a Mnemonic, but at school we were shown a simple way of remembering our nine times tables. If you hold your hands out in front of you and say you want to know what 9 x 3 is, then put your middle finger down on your left hand. You'll have 2 fingers to the left and 7 to the right and the answer is 27!

I was teachings this to the class I'm in yesterday!! They loved it

How I Wish I Could Calculate Pie (3.141593)

or for more decimal places:

How I want a drink, alcoholic of course, after the heavy lectures involving quantum mechanics (3.****)

Also:

China Owls Sometimes Deceive Clay Pigeons (the palaeozoic periods)

Ukele is "My Dog Has Fleas"

One from my school days... Onomatopoeia.. Onomatpoeia ends in a....the last four words first letter gives you the spelling of the difficult part of the word which is the last 4 letters.

What? The ukelele uses notes called M and H?

*head falls off*

Apparently it was a melodic pitch (whatever that is) taught to my mother by some stage act that used ukeles as an easy way to tune the 4 strings. I was always pretty tone deaf so it was lost on me.....
