Answer:
D. Byzantine
Step-by-step explanation:
One of the most important influences on neumatic notation was the Byzantine notation. This notation was developed in the Byzantine empire between the 10th and 12th century. By the late 12th century, the precision of this notation had reached its height, and had adopted the mechanisms that are in place now. This notation consists of signs called "neumes." However, unlike modern neumes, these did not convey pitch, but instead showed the musical interval from the previous tone. The pitch and the length of the starting tone were instead shown by signs known as "martyriai."
