What are the variant nusachot (liturgical formulations) in the Musaf Amidah for Rosh Chodesh, and does one fulfill the obligation if Musaf is replaced by the weekday Shacharit?
Synopsis
Multiple variant formulations exist for the Rosh Chodesh Musaf (zikaron l'chulam hayyu/yihyu/yihye, with or without vekapparat pesha, etc.). If one mistakenly prayed the weekday Shacharit instead of Musaf, one does not fulfill the obligation and must repeat Musaf.
