Ledger Lines (Junior Cert Music): Revision Notes

Ledger Lines

The Musical Alphabet

• Music uses seven letters: A - B - C - D - E - F - G

• Once we reach G, the pattern repeats starting again at A. This happens as we move up or down the stave.

• For example: In the treble clef, the bottom line is E and the top line is F.

• If we go beyond the stave, the note names continue in the same order using ledger lines.

Ledger Lines

• Ledger lines are short lines placed above or below the stave for notes that go higher or lower than the five lines of the stave.
• Ledger lines extend the range of the stave, allowing for higher or lower notes to be written.
• Notes can be written in the space just below the stave (e.g., B), or on ledger lines (e.g., Middle C below the stave or A above the stave).
• As the pitch continues to rise or fall, more ledger lines are added.
• These lines help musicians read very high or very low notes without changing clefs.
