Clefs – Treble, Bass, Alto, Tenor – Interactive Tutorial

The clefs are musical symbols placed at the beginning of the music staff.

There are 3 music clefs : the G clef (treble clef), the F clef (bass clef), the C clef (alto clef, tenor clef)

The clefs are placed very precisely on one of the five lines of the stave. They are setting the name but also the pitch of the music notes.

The G Clef on the Second Line of the Staff (Treble Clef)

The G clef is the most used. It is placed on the second line of the staff. So, the music note placed on the second line of the staff is a G:
