Traditional Ashkenazi practice entailed the recitation of a large number of seliḥot piyyutim in every single one of the Yom Kippur ‘amidot. In many Ashkenazi communities today, these are (excepting Ma’ariv and Ne’ilah) skipped on account of time. But this has always felt like a great shame to me, because seliḥot are, in a sense, the theological and liturgical core of the Yom Kippur practice. So a while back I made a bunch of spreadsheets to compare all the attested Yom Kippur seliḥot rites as listed in Goldschmidt’s maḥzor, and designed an abbreviated cycle of seliḥot for Shaḥarit, Musaf, and Minḥah. Each cycle features two regular seliḥot, one ‘aqedah (a retelling of the binding of Isaac), and one pizmon (a final seliḥah with a repeated refrain, sung communally), for a total of four seliḥot and five repetitions of the thirteen attributes. This is the first result of this process, for Shaḥarit. Musaf and Minḥah selections will arrive eventually, albeit probably not this year.
