Answer:
A clef is a musical symbol used to indicate which notes are represented by the lines and spaces on a musical stave. When a clef is placed on a stave it assigns a particular note to one of the five lines. This line becomes a reference point by which the names of the other notes on the stave are determined.
The bass clef is also called an F clef because it wraps around the highest F note (F3–the F below middle C) on the bass staff. It's usually the second clef that musicians learn after treble, as it is placed on the bottom staff in the grand staff for piano.
