What is the name of the symbol at the beginning of the staff?

The beginning of the staff is called the clef. Generally, the treble clef is called the G clef. The treble clef is drawn starting from the second line of the G note. Generally, treble notation is used for songs, violins, trumpets, etc. The bass clef is called the F clef, and the bass clef is drawn starting from the bass fourth line. The bass score is mostly notated with bass instruments such as cello, bass, and tuba. If it is combined with the treble score to form a large clef, the notation method is more commonly used for piano. There is also an alto clef called the C clef, which is mostly used for notation on the alto clef for French horns, violas, etc.
