Tiberian vocalization
From Freepedia
Tiberian Hebrew is an oral tradition of pronunciation for ancient forms of Hebrew, especially the Hebrew of the Tanakh, that was given written form by masoretic scholars in the Jewish community at Tiberias in the early Middle Ages, beginning in the 8th century. This written form employed symbols, called niqqudot (for vowels) and cantillation signs, added to the Hebrew letters. Though the written symbols came into use in the early Middle Ages, the oral tradition they reflect is apparently much older, with ancient roots.
The Tiberian system of vocalization for the Tanakh represented its own local tradition. Two other local traditions that created written systems during the same period are referred to geographically as the vocalization of the "Land of Israel" (not identical to Tiberias) and the Babylonian vocalization. The former system had little or no historical influence, but the Babylonian system was dominant in some areas for many centuries, and even survives to this day. Unlike the Tiberian system, which mostly places vowel points under the Hebrew letters, the Babylonian system mostly places them above the letters, and is thus called the "supralinear" vowelisation.
As mentioned above, the Tiberian points were designed to reflect a specific oral tradition for reading the Tanakh. Later they were applied to other texts (one of the earliest being the Mishnah), and used widely by Jews in other places with different oral traditions for how to read Hebrew. Thus the Tiberian vowel points and cantillation signs became a common part of Hebrew writing.
