The Emet books (Iyov, Mishlei, Tehillim) have a cantillation system that is not used elsewhere in Tanach. In addition to the use of cantillation marks not found elsewhere (iluy, ole, dehi, geresh muqdam), the marks that are also used elsewhere appear to have different grammatical function when used in the Emet books. For instance, Psalm 1:1 ends with the phrase:
וּבְמוֹשַׁ֥ב לַ֝צִ֗ים לֹ֣א יָשָֽׁב׃
Normally, the revia' on לַ֝צִ֗ים would be a strong disjunctive, but that makes little sense grammatically in this context. I'm assuming that somehow the geresh muqdam here alters the function of the revia' to be either a weaker disjunctive or a conjunctive.
Can anyone point me to a reference that describes the grammatical rules of the te'amim in the Emet books? On-line information would be most appreciated.
