The evening service is called “Kol Nidre” it is also the name of the famous prayer. The cantor chants Kol Nidre which is hundreds of years old and unlike any other prayer that we hear in synagogue.
Kol Nidrey ve-esarey va-ha-ramey v’konamey v’hinu-yey v’kinusey u-sh’vuot, di-n’darna u-d’ish-t’vana, u-d’ah-rimna, v’di-asarna al naf-sha-tana mi-yom kipurim sheh-avar ad yom kipurim zeh ha-ba aleynu l’tovah, kol-hon ih-ratna v’hon, kol-hon y’hon sharan. Sh’vikin, sh’vitin, b’teylin u-m’vutalin, la sh’ririn v’la ka-yamin Nidrana la nidrey, ve-esarana la esarey, u-sh’vuatana la sh’vuot.
All vows, oaths, and promises which we made to G-d from last Yom Kippur to this Yom Kippur and were not able to fulfill – may all such vows between ourselves and G-d be annulled. May they be void and of no effect. May we be absolved of them and released from them. May these vows not be considered vows, these oaths not be considered oaths, and these promises not be considered promises.
