On which line is the bass clef placed on the musical staff?

The bass clef is placed on the fourth line of the musical staff. This clef indicates the range of low notes and is often used for instruments such as the bass guitar, trombone, and cello, as well as for the left hand in piano music. By placing the bass clef on the fourth line, that line represents the note F, providing a foundation for identifying other pitches on the staff.

This positioning is crucial for musicians as it helps in reading and interpreting music by establishing a point of reference for the notes below and above the fourth line. Understanding this aspect of the bass clef allows musicians and students to accurately read music, helping them to play their instruments or sing in tune.
