Gradual is composed of Respond and Verse. Gradual leads the chorus with each passage of Psalm as a vocal solo, and a choir responds the chorus with a main part starting as Respond. After then, a vocal solo sings the Verse(Psalm Verse), a choir responds the final passage with him. However, a repeat of Respond in Gradual was disappeared from 9C to 12C.
The Formula of Gradual is Intonation, Flex, Mediant, and Termination. That is, a Formula in Respond is Intonation and Flex, a Formula of Verse is Mediant and Termination.
This thesis treats Part Ⅰ, Respond and Part Ⅱ, Verse in Gradual as a main. These are about LU(Liber usualis) 1048, Beata in Mode Ⅰ; LU 1269, Tollite in Mode Ⅱ; LU 1654, Benedicite in Mode Ⅲ; LU 1207, Domine in Mode Ⅳ; LU 1037, Bonum in Mode V; LU 478, Benedictus in Mode Ⅶ; LU 1216, Dilexisti in Mode Ⅷ.
Intonation and Flex, Part I of Gradual that is analyzed formerly is arranged as follows. Intonation is composed of motive X(F-G-A, Ex. 15) as a common axis among all the modes, except for Mode Ⅵ. Though there is a fixed common axis that is a motive X, each mode is variated by other cadences and composed of a special quality of each mode. Flex is used for variation motive X(Ex. 19) as a common axis of all modes (except for Mode Ⅵ).
These motives are composed of the same function, pitch, variation motives and constructed of a special quality of each mode as symmetry, the same pattern progress, inversion or retrograde relation and permutation.
