I thought this might be a good place to ask...
DD has music homework. She has been given the note letter names, and has to write them on the stave, eg A, C, G E etc. No problem with this.
However, some of the note letter names have a small mark by them, like an apostrophe. What does this mean?
E'
B'
and so on.
I have never come across this, and I can't find anything online.
