Alejandro Enrique Planchart
Recent reinterpretations of the evidence on early transmission Gregorian chant point to a larger role for written sources than had previously been thought. Evidence trope repertories-the ordered entire series number feasts over considerable period time-points similar conclusions. Variations in from one region another existence general regional traditions. Since tropes did not posses authority itself, they were acclimatized each order make them conform local traditions, which seem have their roots sung locality before adoption Roman liturgy and chant. The nature acclimatizations, both textual musical, indicate that often received form then changed manipulated ways themselves suggest dependency upon text music.
