<P> Regardless, all halachic authorities teach that one should follow one's community's custom . </P> <P> It is customary to hear 100 or 101 sounds in the synagogue, although the minimum requirement is to hear 30 sounds . </P> <P> The shofar is sounded just before, during and after the Musaf prayer on Rosh Hashanah . For the sounding just before Musaf, after the Torah reading, relevant verses from the Bible are recited, followed by two blessings: one on the Biblical commandment of "hearing the sound of the shofar" and the blessing of Shehecheyanu . After that, thirty shofar blasts are sounded . In the Musaf prayer itself, the shofar is sounded three times during the silent prayer, and then again three times during the leader's repetition . For each of these soundings, ten appropriate selections from the Bible are recited, followed by a benediction, followed finally by a series of ten shofar blasts . After leader's repetition of the Musaf prayer is completed, a final series of ten (or eleven, depending on the community's custom) shofar blasts are sounded, yielding a total of 100 or 101 blasts . (Some communities do not blow the shofar during the silent Musaf prayer, instead blowing the 30 blasts after the leader's repetition .) After the service is over, it is customary to blow another series of thirty blasts "to confuse the Adversary". </P> <P> According to the Sephardic tradition, a full 101 blasts are sounded, corresponding to the 100 cries of the mother of Sisera, the captain of Jabin's army who did not return home after being killed by Yael (Judges 5: 28). One cry is added to symbolize the legitimate love of a mother mourning her son . </P>
