Is there a highest and lowest note that can be written on sheet music without using the one or more octave higher/lower notation? In my case for the piano specifically.
I want to learn to sight read and my first goal is to be able to name any note that appears on sheet music so that I don't have to count from a known position. Therefore I need to know all notes that could appear. Are there any rules about that? Can the highest and lowest notes on the piano be written without using the octave higher/lower notation?
Is there no standard for sheet music notation? I'm creating some very simple software to generate notes to help me practice but I don't want it to generate total nonsense which I'll never see in the real world. Are there any standards I could look up?
