The Tiberian system spread quickly and was accepted in all communities by the 13th century. Each community re-interpreted its reading tradition so as to allocate one short musical motif to each symbol: this process has gone furthest in the Western Ashkenazi and Ottoman (Jerusalem-Sephardi, Syrian etc.) traditions. Learning the accents and their musical rendition is now an important part of the preparations for a bar mitzvah, as this is the first occasion on which a person reads from the Torah in public.
