If you were helping a new player (1 year or less) to rehearse a piece of music containing E# or B# how would you explain the note? Would you say it is an F natural or a C natural? Or would you say it sounds the same and has the same fingering but has a different name? Or something else? I'm faced with this sort of question quite often, and I want to give an accurate answer, but without being confusing or appealing to concepts of scales that the student might not have. I particularly don't want to give the impression that music theory is hard, as an early bad experience of music theory (like maths at school) could be enough to put someone off for life. Suggestions please!
