Question AboutDouble Flats and Double Sharps??

[bmcdancer]

I WAS GIVEN A BLANK KEYBOARD AND I WAS ASKED TO FIND THE SHARPS, FLATS, DOUBLE FLATS AND DOUBLE SHARPS. CAN ANY ONE EXPLAIN THIS TO ME??

EXAMPLE: THE "D" CHORD IS SUPPOSE TO BE Ebb, D, AND Cx (HOW DID THEY GET THIS?)

I don't think they mean chords here, they mean notes.

D = Ebb = C##

They are enharmonic equivalents, they are the same note.

For example let's take D and move it up in half steps:

D D# E yes?

Or we could simply say D D# D##.

D## = E

So take E and mopve it down in half steps

E Eb D

Or E Eb Ebb

And C up in half steps C C# C##

Both ways here we arrive at the same note but just have different names for it Ebb D and C##

Hope that helps.
