I apologize if this is an overly obvious question, but I have been having difficulty finding the answer here or elsewhere.
I am making a deck of sheet music flash cards for use with piano, and I am trying to memorize note names including octaves for rapid recall. For C# on Octave 4, would the correct way to name the note be:
- C#4 ("C-Sharp-Four")
- C4# ("C-Four-Sharp")
I have seen examples of both in the resources I have used.
