Is there a ritual when Jews read the Torah?

Answer 1

Depends how religious they are. It could be everyday or just once a year.

Answer 2

Before torah study, Jews should say a blessing. Two are particularly relevant here, one thanks God for commanding us to study the Torah, the other thanks God for giving the Torah. These blessings can be said quietly with no particular ritual before private study, but if you're called up to a reading from the Torah scroll during a synagogue service, there's a nice musical way to chant the "giving the Torah" blessing, and a related blessing, also musical, sad at the end of the section you're called up for. With each of these blessings, it's traditional to touch your tzitzit (the fringe of your prayer shawl) to the text at the point where it is read and kiss your tzitzit. This is to kiss the text without touching the text.

Then, there's the ritual of the reading itself. You can read the Torah in a normal tone of voice, but during a synagogue service, there is a traditional liturgical chant, rather musical sounding, that is used.
