The treble clef, also called the "G clef," resembles an abstracted form of the letter G. The lower curve wraps around the next-to-lowest line on the staff indicating the note G. the five lines together represent E, G. B, D and F, while the spaces between the lines represent F, A, C and E.
Most Western music uses two staves, the treble clef and the bass clef, represented by two groups of five lines each. Other, less commonly used clefs, such as the alto clef, also use a five-line staff but place the same notes at different points on the staff.
Singers and instrumentalists whose range encompasses the range from middle C upward generally read from the treble clef instead of the bass clef. Violinists, for instance, use the treble clef to the extent that music theorists have sometimes dubbed it the "violin clef."
