There are lots of different music clefs in music theory, such as Soprano clef, Mezzo-Soprano clef, Subbass clef, etc. But we are here to discuss the four main music clefs, which are Treble, Alto, Tenor and Bass clef, which are common in SATB writing, either in open score or closed score.Â
The open score simply just separates every voice part to Soprano, Alto, Tenor, and Bass into each individual part, whereas the closed score is to combine Soprano and Alto, Tenor and Bass into only two staves (Treble and Bass Clef).Â

If you pay attention to the tenor clef, there is an “8” sign below the treble clef, it means anything written on that stave has to be lower down an octave.

Why there are so many clefs?
The reason for having clefs is to avoid reading so many ledger lines for the players. Another reason will be ranges for different instruments.
Imagine a pianist only needs to know how to read one clef, and the ranges for piano are extremely wide, then the pianist requires a longer time to read the notes as he/she plays the piano, therefore the performance will definitely be affected.Â
