quick question

[tomac62]

c flat is B isn't it. And does it matter whether you say A sharp or B flat?

[_Chris_]

Yes.
No.

You wouldn't normally refer to B as C flat though. Although sometimes you may need to when writing theory.

1. Yes.
2. Well, if you're talking about the note itself, then no, it's the same note. But, when talking about the note in a SCALE, it does. You can' mix sharps and flats in the key signature. For example, the F major scale has a B flat, not an A#, G major has an F sharp, not a G flat, D major has an F# and a C#, not Gb and Db and so on. If you learn the circle of fifths, this won't be a problem. :)

Correct - alone either name is okay being that they are enharmonic equivalents of each other - and though Cb is rare, it is the 4th degree in Gb major - same as E# if the 7th in F# major - rare & goofy, but valid
