RHY.2:12 - Relations
RHY.1 selects the working difficulty. RHY.3 uses the retained carrier–articulation relation, and RHY.4 examines timing correspondences. RHY.5–RHY.8 use the account for representation, translation, comparison and possible variants.
A.22 supplies the general structure distinction; C.27.TA qualifies a temporal claim; C.2.1 governs the account’s relation to its subject and evidence. NOT.1 asks which distinctions an expression must preserve. RHY.2 supplies the rhythmic distinctions before that notational design.
