Cantillation, Cantillation

Very roughly speaking, each word of text has a cantillation mark at its primary accent and associated with that mark is a musical phrase that tells how to sing that word. The reality is more complex, with some words having two or no marks and the musical meaning of some marks dependent upon context. There are different sets of musical phrases associated with different sections of the Bible. The music varies with different Jewish traditions and individual cantorial styles.

However, the Ashkenazic yeshiva known as Aderet Eliyahu, or (more informally) Zilberman's , in the Old City of Jerusalem, uses an adaptation of the Syrian cantillation-melody for these books, and this is becoming more popular among other Ashkenazim as well.
