What is the primary use of the treble clef in music?

The treble clef is primarily used to notate higher-pitched instruments and voices. It indicates the notes that are typically found in the upper range, which include instruments such as the flute, clarinet, trumpet, and violin, as well as higher vocal parts like soprano and alto. The treble clef is positioned on the second line of the staff, which represents the note G above middle C, allowing for clear representation of notes that are usually played or sung at higher registers. This makes it essential for music written specifically for those instruments and voice types, as it helps performers easily identify the pitches they are to play or sing.

In contrast, other options relate to different aspects of music notation. The use for lower-pitched instruments and voices utilizes a different clef, such as the bass clef. Indicating notes below middle C isn't the focus of the treble clef, which centers on higher pitches. Finally, while rests are an important part of music notation, they are denoted through specific symbols and not through clefs like the treble clef, which is specifically concerned with indicating pitch.
