Tekiah! Teruah! Shevarim! Tekiah Gedolah!
In the traditional liturgy, the special character of each holiday is particularly conveyed by the piyyutim (hymns, liturgical poems) that are recited or chanted on that day. Most of these piyyutim have been omitted in Reform liturgies since the nineteenth century, out of a sense that their Hebrew diction is too arcane and their theology too medieval. Yet, some of these poems have routinely been retained in Reform High Holy Day prayer books, particularly for Yom Kippur.
The “Days of Awe” is a good name for the High Holiday season because when we are in awe of something, that's a good thing, but I like “Awesome Days” so much better.
