The treble clef is a musical symbol used to indicate the pitch of written notes. It is placed at the beginning of a staff and designates the second line from the bottom as the note G. This helps musicians read and play higher-pitched notes, commonly found in instruments like the violin, flute, and the trumpet. In sheet music, the treble clef is essential for understanding melodies and harmonies. It is often used in vocal music for soprano and alto parts, as well as in many popular music genres. The clef's distinctive swirl makes it easily recognizable in musical notation.
