By the tenth century C.E., the chant in use in Judah had clearly become more complex, both because of the existence of "pazer", "geresh" and "telisha" motifs in longer verses and because the realization of a phrase ending with a given type of break varied according to the number of words and syllables in the phrase. The Tiberian Masoretes therefore decided to invent a comprehensive notation with a symbol on each word, to replace the fragmentary systems previously in use. In particular, it was necessary to invent a range of different conjunctive accents to show how to introduce and elaborate the main motif in longer phrases. (For example, "tevir" is preceded by "mercha", a short flourish, in shorter phrases but by "darga", a more elaborate run of notes, in longer phrases.) The system they devised is the one in use today, and is found in Biblical manuscripts such as the Aleppo Codex. A Masoretic treatise called "Diqduqe ha-teʿamim" (precise rules of the accents) by Aaron ben Moses ben Asher survives, though both the names and the classification of the accents differ somewhat from those of the present day.
