Songs and Dances for Shavuot
Shavuot conjures up images of the giving of the Torah, harvesting, going out into the fields, eating dairy and staying up all night studying. So it's only natural that songs associated with Shavuot inlcude many of these themes: nature, learning and foods having to do with Israel.
The following website contains the lyrics (and some musical snippets) of songs in Hebrew, English and Yiddish, having to do with the themes of Shavuot.
