What are ledger line notes?
A ledger line or ledger line is used in Western musical notation to notate pitches above or below the lines and spaces of the regular musical staff. A line slightly longer than the note head is drawn parallel to the staff, above or below, spaced at the same distance as the lines within the staff.
What are the ledger lines in bass clef?
Ledger lines are super simple. They are the little lines that go above or below the staff. Each staff (treble and bass) has 5 lines and 4 spaces. But we know the keyboard has a lot more notes than that, so ledger lines are used to show notes that go beyond the staff.
