Guido of Arezzo - established a staff of 4 lines, 2 of which
stood out in color, yellow or green being used for the do
tone + ted for the fa tone. The 4 lines + 3 spaces
were sufficient for the music of his time.
Our modern 5 line stavewas fully in use for
nearly all kinds of music by the end of the 15th C.
The modern symbols for the notes themselves evolved
from the medieval neumes.
Bass clef - marked the line for the note F, + its shape
was that of a stylized F.
Treble clef - marked the line for the note G, + its shape
was that of a stylized G.

Aquare or quadratic notation on 4 line red staves. This notation
which developed out of the early neumes, had crystallized by the
12th or 13th C. + has since become the basis of our modern notation.
The neumes had no rules for measuring time, as rythm was
determined by the Latin prose of teh texts.
