baritone clef

1. A old version of the F clef that locates f (below middle C) on the third line. 

 

Also [Eng.] F clef; [Fr.] clef de fa (f); [Ger.] F-Schlüssel  (m); [It.] chiave di basso  (f); [Sp.] clave de fa (f).

 

2. There is also a rarely used baritone clef in the C clef. This clef puts middle C on the top line of the staff. This creates the same placement of notes as the baritone clef in the F clef. So both baritone clefs are essentially the same notation using different clefs.
