What do neumes 4-line staff FC or G clef?

Neumes are early musical notations used to indicate pitch and rhythm in medieval music. A 4-line staff, often associated with Gregorian chant, provides a framework for placing these neumes, with specific lines representing pitches. The F clef (also known as the bass clef) and G clef (treble clef) are modern symbols that indicate the pitch of notes on a staff, with the F clef marking the fourth line as F and the G clef marking the second line as G. Together, these elements help musicians read and interpret the music accurately.
