Standard musical notation has come a long way:

The treble clef is a standardized representation of the letter G, while the bass clef, also known as the F-clef, is a more dramatic unrecognizable evolution of the letter F. A possible addition to this evolution was suggested in a 1908 article in The Musical Times, which argued that the contemporary form of the treble clef is a result of 17th century notational technique in which multiple symbols was used indicate both pitch and vocal sound, with “G, Sol” being a common combination that was eventually shortened to G.S. and then “gradually corrupted by careless transcription” into the treble clef.
