Just remembered a German one I learnt as a wee lad forced into violin lessons: The strings on a violin have basic tones G,D,A,E, the German mnemonic used to make that easy to remember is "Geh, Du Alter Esel". (Go, you old donkey).[I]..[/I][/QUOTE]
And from my early "musical" days:

treble cleff line notes (bottom to top): Every Good Boy Does Fine

Staying with music theory:

Father Christmas Goes Down An Escalator Backwards

for the sharps in their correct order.

"Father Christmas" was the name by which we knew Santa Claus when we were youngsters growing up in Britain. The mnemonic was apparently my violin teacher's own invention.

I learnt: Every Good Boy Deserves a Favour

David

Father Charles Goes Down And Ends Battle

Battle Ends And Down Goes Charles's Father

which does the sharps and flats in a nicely palindromic way

Don't know if the eight planets mneonics have been mentioned,
but My Very Educated Mother Just Served Us Nine Plums is
now out of date. Cavalierly ignoring Pluto might result in a
simple mod: (she) just served us nothing (perhaps as a show
of support for nine planets).

By another interpretation there could be 11 planets.

[QUOTE]The IAU decided that Pluto and Eris should be reclassified as dwarf planets. The asteroid Ceres meets those requirements, so it’s a dwarf planet too.

So, how many planets in the Solar System? Until a new, large object is discovered out beyond Pluto, there are only 8 planets, and 3 dwarf planets.[/QUOTE]

Now how can anyone say this would sound different in D flat major?

well if my memory serves me correct they would be multiplying the average frequency by 2^(1/12) = 1.5 if I remember my laws of strings that I read after the physics 11 high school exam I think.

Sound the same but notated differently:

[CODE]C#, D#, E#, F#, G#, A#, B#, C#
Db, Eb, F, Gb, Ab, Bb, C, Db[/CODE]

[root]major scale has 2,2,1,2,2,2,1 for the spacing.
[root]major chord has spacing 4,3

I tried teaching my uncle some basics about chords and guitar when he was living here with a broken wrist ( I know kinda pointless).
