Which clef signifies lower-pitched instruments and voices?

The bass clef is specifically designed for notating lower-pitched instruments and voices, making it essential for musicians who play instruments like the cello, bass guitar, or trombone, as well as for the bass range of vocalists such as bass singers and baritones. In the bass clef, the notes are positioned on the staff in a way that denotes lower pitches, with the clef symbol indicating that the fourth line of the staff corresponds to the note F2. This is in contrast to the other clefs, which cater to higher pitches or different registers. For instance, the treble clef is used for higher pitches, while the alto clef serves primarily for instruments such as the viola, which have a range between treble and bass. The soprano clef, though less common, is also geared towards high vocal ranges. Thus, the bass clef is distinctly used for lower-pitched contexts.
