Cantillation is the ritual chanting of readings from the Hebrew Bible in synagogue services. The chants are written and notated in accordance with the special signs or marks printed in the Masoretic text of the Hebrew Bible (or Tanakh) to complement the letters and vowel points.
These marks are known in English as accents, notes or trope symbols, and in Hebrew as טעמי המקרא ta`amei ha-mikra or just טעמים te`amim. Some of these signs were also sometimes used in medieval manuscripts of the Mishnah. The musical motifs associated with the signs are known in Hebrew as niggun or neginot (not to be confused with Hasidic nigun) and in Yiddish as טראָפ trop: the word trope is sometimes used in English with the same meaning.
Three systems of Hebrew punctuation (including vowels and cantillation symbols) have been used: the Babylonian, the Palestinian and the Tiberian, only the last of which is used today.
Babylonian Biblical manuscripts from the Geonic period contain no cantillation marks in the current sense, but small Hebrew letters are used to mark significant divisions within a verse. Up to eight different letters are found, depending on the importance of the break and where it occurs in the verse: these correspond roughly to the disjunctives of the Tiberian system. For example, in some manuscripts the letter tav, for tevir (break), does duty for both Tiberian tevir and zaqef. In general there are no symbols for the conjunctives, though some late manuscripts use the Tiberian symbols for these. There is also no equivalent for low-grade disjunctives such as telishah gedolah: these are generally replaced by the equivalent of zaqef or revia.
Nothing is known of the musical realization of these marks, but it seems likely that they represent breaks or variations in a set melody applied to each verse. (A somewhat similar system is used in manuscripts of the Qur'an to guide the reader in fitting the chant to the verse: see Qur'an reading.)
