For other uses, see Ledger line (tombstone).
Notes in ledger lines above the staff. The four notes on the right might, for some instruments, be considered too far above the staff and written, instead, in 8va notation.

A ledger line or leger 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 (see Figure 1).

The origin of the word is uncertain, but may have been borrowed attributively from the term used to describe a horizontal timber in a scaffolding, lying parallel to the face of the building and supporting the putlogs. There is no basis to support the often-found claim that the word originates from the French léger, meaning "light" or "slight" (OED 2005). The Oxford online dictionary describes the origin of the "leger" spelling as a "variant of ledger" that first appeared in the 19th century (Oxford Living Dictionary n.d.).

Although ledger lines are found occasionally in manuscripts of plainchant and early polyphony, it was only in the early 16th century in keyboard music that their use became at all extensive (Anon. 2001). Even then printers had an aversion to ledger lines which caused difficulties in setting type, wasting space on the page and causing a messy appearance. Vocal music employed a variety of different clefs to keep the range of the part on the staff as much as possible; in keyboard notation a common way of avoiding ledger lines was the use of "open score" on four staves with different clefs (Godwin 1974, 16–17).

Except for woodwind players, who prefer ledger lines to 8va notation because they associate fingerings with staff positions (Shatzkin 1993, 48), notes that use at least four ledger lines make the music illegible.[citation needed] In order to prevent this issue, the composer would usually switch clefs or use the 8va notation. Some transposing instruments, such as the piccolo, double bass, guitar, and the tenor voice, transpose at the octave to avoid ledger lines.

Notation of tuba, trombone, and euphonium parts always use ledger lines below the bass staff, and never the 8va bassa notation (Read 1969, 354).

When music for bass clef instruments, such as the cello or trombone, goes several ledger lines above the bass clef, the tenor clef is used; if it were to go even higher than practical in tenor clef, the notes may be notated in treble clef, or in the case of trombone, alto clef.[citation needed]

A ledger line is also used to support a half rest half rest or whole rest whole rest where there are multiple voices on one staff and such a rest is forced above or below the staff. (The rare double whole rest is suspended between two ledger lines in this situation.)
