=== Ledger Lines ===

Sometimes notes have pitch lower or higher than the lowest or highest line of the staff. To accommodate this, the notation uses '''Ledger Lines''', additional lines drawn above or below the staff. Unlike the staff, however, ledger lines are short line fragments that are only as long as necessary for one or several consecutive notes that do not fit on the staff. The number of lines drawn is however many are necessary to get from the lowest note on the staff to the note desired - in some cases it can be a lot.
