I may be way out in this, but shouldn't it be more correct to mention e# when you talk about the the key-note A and its augemented fifth (e#) in let's say the major scale. Because the F doesn't appear in the scale and by using the e# you overcome that problem.. Am I right? :(

It's the same, I think, when you mention the diminished seventh of C, which should be named as bbb. :eek:

I may be wrong, though.. :confused:
