Et sha'are ratson

Et sha'are ratson (עֵת שַׁעֲרֵי רָצוֹן) is a piyyut on the Binding of Isaac, written in the 12th century by Judah ben Samuel ibn Abbas of Fez. It is recited prior to the sounding of the shofar in the Sephardic and Mizrahi Rosh Hashanah services.

In the traditional Spanish and Portuguese liturgy, it is associated with an ancient Morisco chant, characteristic of its origin in the southern cities of Spain. This can be observed in the prominence of the third and fifth degrees of the scale, and in the combination and repetition of brief phrases in sentences of different lengths.
