The only G-clef still in use is the [[Treble (sound)|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.<ref>{{Cite journal |last=Greer |first=Amy |date=2003 |title=In Praise of Those Grass-Eating Cows |journal=[[American Music Teacher]]|volume=53 |issue=1 |pages=22–25 |jstor=43547681 }}</ref> 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 [[violin]], [[flute]], [[oboe]], [[cor anglais]], all [[clarinets]], all [[saxophones]], [[French horn|horn]], [[trumpet]], [[cornet]], [[vibraphone]], [[xylophone]], [[mandolin]], [[recorder (musical instrument)|recorder]], [[bagpipe]] and [[guitar]]. [[Euphonium]] and [[baritone horn]] are sometimes treated as transposing instruments, using the treble clef and sounding a major ninth lower, and are sometimes treated as concert-pitch instruments, using bass clef. The treble clef is also the upper staff of the [[grand staff]] used for [[harp]] and [[keyboard instrument]]s. Most high parts for bass-clef instruments (e.g. [[cello]], [[double bass]], [[bassoon]], and [[trombone]]) are written in the tenor clef, but very high pitches may be notated in the treble clef. The [[viola]] also may use the treble clef for very high notes. The treble clef is used for the [[soprano]], [[mezzo-soprano]], [[alto]], [[contralto]] and [[tenor]] voices. Tenor voice parts sound an octave lower and are often written using an octave clef (see below) or a double-treble clef.
