, a C-clef fixes middle C, and a G-clef fixes the G above middle C. In modern music notation, the G-clef is most frequently seen as treble clef (placing G4 on the second line of the stave), and the F-clef as bass clef (placing F3 on the fourth line). The C-clef is mostly encountered as alto clef (placing middle C on the third line) or tenor clef (middle C on the fourth line). A clef may be placed on a space instead of a line, but this is rare. The use of different clefs makes it possible to write music for all instruments and voices, regardless of differences in

Placement on the stave

Theoretically, any clef may be placed on any line. With five lines on the stave and three clefs, there are fifteen possibilities for clef placement. Six of these are redundant because they result in an identical assignment of the notes to the lines (and spaces)—for example, a G-clef on the third line yields the same note placement as a C-clef on the bottom line. Thus, there are nine possible distinct clefs, all of which have been used historically: the G-clef on the two bottom lines, the F-clef on the three top lines, and the C-clef on any line except the topmost. The C-clef on the topmost line is equivalent to the F-clef on the third line but both options have been used. Each of these clefs has a different name based on the

for which it is best suited. In modern music, only four clefs are used regularly:

Individual clefs

This section shows a complete list of the clefs, along with a list of instruments and voice parts notated with them. A dagger (†) after the name of a clef indicates that the clef is no longer in common use.


G-clefs


Treble clef

The only G-clef still in use is the treble clef, with the G-clef placed on the second line. This is the most common clef in use and is generally the first clef learned by music students. For this reason, the terms "G-clef" and "treble clef" are often seen as synonymous. The treble clef was historically used to mark a treble, or pre-pubescent, voice part. Instruments that use the treble clef include

French violin clef

A G-clef placed on the first line is called the French clef, or French violin clef. This clef was used in the seventeenth and eighteenth centuries in France for violin music and flute music.


F-clefs


Baritone clef

When the F-clef is placed on the third line, it is called the baritone clef. Baritone clef was used for the left hand of keyboard music (particularly in France; see

. This can also be indicated with two overlapping G-clefs. Tenor banjo is commonly notated in treble clef. However, notation varies between the written pitch sounding an octave lower (as in guitar music and called octave pitch in most tenor banjo methods) and music sounding at the written pitch (called actual pitch). An attempt has been made to use a treble clef with a diagonal line through the upper half of the clef to indicate octave pitch, but this is not always used. To indicate that notes sound an octave higher than written, a treble clef with an ''8'' positioned above the clef may be used for penny whistle, soprano and sopranino recorder, and other high woodwind parts. A treble clef with a ''15'' above (sounding two octaves above the standard treble clef) is used for the garklein (sopranissimo) recorder. An F-clef can also be notated with an octave marker. While the F-clef notated to sound an octave lower can be used for contrabass instruments such as the

to the lines and spaces of the stave. With the exception of some common drum-kit and marching percussion layouts, the assignment of lines and spaces to instruments is not standardised, so a legend is required to show which instrument each line or space represents.

are notated in bass clef and mallet percussion instruments are noted in treble clef or on a grand stave. If the neutral clef is used for a single percussion instrument the stave may only have one line, although other configurations are used. The neutral clef is sometimes used where non-percussion instruments play non-pitched extended techniques, such as hitting the body of a string instrument, or having a vocal choir clap, stamp, or snap. However, it is more common to write the rhythms using × noteheads on the instrument's normal stave, with a comment to indicate the appropriate rhythmic action.

in place of ordinary notes. This TAB sign is not a clef — it does not indicate the placement of notes on a stave. The lines shown are not a music stave but rather represent the strings of the instrument (six lines would be used for guitar, four lines for the bass guitar, etc.), with numbers on the lines showing which fret should be used.


History

Before the advent of clefs, the reference line of a stave was simply labeled with the name of the note it was intended to bear: ''F'', ''C'', or sometimes ''G''. These were the most common 'clefs', or (key-letters), in Gregorian chant notation. Over time the shapes of these letters became stylised, leading to their current versions. Many other clefs were used, particularly in the early period of chant notation, keyed to many different notes, from the low ''Γ'' (''gamma'', the G on the bottom line of the bass clef) to the G above middle C (written with a small letter ''g''). These included two different lowercase ''b'' symbols for the note just below middle C: round for B, and square for B. In order of frequency of use, these clefs were: ''F'', ''c'', ''f'', ''C'', ''D'', ''a'', ''g'', ''e'', ''Γ'', ''B'', and the round and square ''b''. In later medieval music, the round ''b'' was often written in addition to another clef letter to indicate that B rather than B was to be used throughout a piece; this is the origin of the
key signature In Western musical notation, a key signature is a set of sharp (), flat (), or rarely, natural () symbols placed on the staff at the beginning of a section of music. The initial key signature in a piece is placed immediately after the clef at ...
. In the polyphonic period up to 1600, unusual clefs were occasionally used for parts with extremely high or low tessituras. For very low bass parts, the Γ clef is found on the middle, fourth, or fifth lines of the stave (e.g., in

’s Requiem and in a mid-16th-century dance book published by the Hessen brothers); for very high parts, the high-D clef (''d''), and the even higher ''ff'' clef (e.g., in the '' Mulliner Book'') were used to represent the notes written on the fourth and top lines of the treble clef, respectively. The practice of using different shapes for the same clef persisted until very recent times. The F-clef was, until as late as the 1980s in some cases (such as hymnals), or in British and French publications, written like this: In printed music from the 16th and 17th centuries, the C clef often assumed a ladder-like form, in which the two horizontal rungs surround the stave line indicated as C: ; this form survived in some printed editions ( see this example, written in four-part men's harmony and positioned to make it equivalent to an octave G clef) into the 20th century. The C-clef was formerly written in a more angular way, sometimes still used, or, more often, as a simplified ''K''-shape when writing the clef by hand: In modern Gregorian chant notation the C clef is written (on a four-line stave) in the form and the F clef as The flourish at the top of the G-clef probably derives from a cursive ''S'' for "sol", the name for "G" in solfege. C clefs (along with G, F, Γ, D, and A clefs) were formerly used to notate vocal music. Nominally, the soprano voice parts were written in first- or second-line C clef (''soprano clef'' or ''mezzo-soprano clef'') or second-line G clef (''treble clef''), the alto or tenor voices in third-line C clef (''alto clef''), the tenor voice in fourth-line C clef (''tenor clef'') and the bass voice in third-, fourth- or fifth-line F clef (''baritone'', ''bass'', or ''sub-bass clef''). Until the 19th century, the most common arrangement for vocal music used the following clefs: * Soprano = soprano clef (first-line C clef) * Alto = alto clef (third-line C clef) *Tenor = tenor clef (fourth-line C clef) * Bass = bass clef (fourth-line F clef) In more modern publications, four-part music on parallel staves is usually written more simply as: * Soprano = treble clef (second-line G clef) * Alto = treble clef * Tenor = treble clef with an ''8'' below ''or'' a double treble clef. Many pieces, particularly those from before the 21st century, use an unaltered treble clef, with the expectation the tenors will still sing an octave lower than notated. * Bass = bass clef (fourth-line F clef) This may be reduced to two staves, the soprano and alto sharing a stave with a treble clef, and the tenor and bass sharing a stave marked with the bass clef.


Further uses

Clef combinations played a role in the modal system toward the end of the 16th century, and it has been suggested certain clef combinations in the polyphonic music of 16th-century vocal polyphony are reserved for authentic (odd-numbered) modes, and others for plagal (even-numbered) modes, but the precise implications have been the subject of much scholarly debate. Reading music as if it were in a different clef from the one indicated can be an aid in transposing music at sight since it will move the pitches roughly in parallel to the written part. Key signatures and accidentals need to be accounted for when this is done.
