an a flat only can be called an a flat
There is no double sharp equivalent, but it is the same as G sharp.
no, g sharp is the only "landlocked" note, which means it can only be called g sharp or a flat, not any double sharps or double flats.
It is called a "natural" sign, and it cancels out/naturalizes a sharp or a flat.
No. It would be F#X or Bb bb. (F sharp double-sharp or B flat double-flat.)
Being that it's a whole-step away from another sharp or flat note in both directions, there is no possible double-sharp/flat spelling for it.
I am guessing so... I've seen something like a key signature having a B-flat, and somewhere in the piece there is a flat in front of a B, so it would be a B-double-flat. If double flats are allowed,then it would be C,B-sharp;C-sharp,D-flat;D, E-double-flat; D-sharp, E-flat; E, F-flat;F,G-double-flat;F-sharp,G-flat;G,A-double-flat;G-sharp,A-flat;A,B-double-flat;and B,C-double-flat.
It's because that note is the only one two half-steps away from another flat/sharp note in both directions.
E flat (or D sharp)
Enharmonics is the name for a pitch that is "spelled" three different ways. # C=B sharp, D double flat # D flat= C sharp, B double sharp....
A note which is neither sharp nor flat is called natural.A natural
Offhand, I would say that is a misprint. However, a natural and flat means to return to a normal flat note after a double-flat. For example, suppose you are in a key with B-flat in the key signature, but you have an E-flat diminished chord, which includes B-double-flat. After that you have a regular B-flat. The natural cancels the double-flat, and the single flat returns to the usual note. After a double-sharp, a natural and sharp would do the same thing.
It's not equivalent to any sharp, but it is equivalent to D double sharp.
The equivalent of an f sharp is a G flat.
