Ani hu ha-sho'el is a Selicha piyyut for Yom Kippur; in most rites, but not all, it is recited in the Musaf service. It is composed by Rabbi Baruch ben Samuel of Mainz. As is common in Selichot for Musaf, the Selicha describes the Yom Kippur service in the Temple and the loss since the destruction of the Temple. In many communities, it is recited aloud by the Hazzan with a moving melody. Usually, even in communities where it is customary to recite the Selichot on a multi-year cycle and to choose only some of the Selichot each year, this Selicha is recited each year.
