When you run out of lines on a musical staff, you can use ledger lines. These are short lines added above or below the staff to extend the range of notes that can be notated.
There are 11 lines and 10 spaces in a grand staff.
5, but these can be extended above and below the stave.
They are called staff lines. Or just called a Staff. I am glad to help.
