Halakhah su Salmi 98:76

There is considerable discussion and controversy among early authorities with regard to the details of the performance of this mizvah and as to when the trumpets are to be blown alone and when together with the shofar as indicated in Psalms 98:6, "With trumpets and the voice of the shofar shall you sound the teru'ah before the King, God." Some authorities maintain that the trumpets together with the shofar are to be sounded only on the Temple Mount; in other locales the shofar alone is to be blown. Rabbi Frank explains that this opinion is based upon Numbers 10:9, "… and you shall be remembered before the Lord your God." According to this line of reasoning, only the Temple site is considered to be "before God." Nowadays, considerations of ritual purity preclude entry onto the Temple Mount. Rabbi Frank, however, brings evidence that all of Jerusalem is considered to be an extension of the Temple with regard to the sounding of trumpets. He adds that the shofar need not be sounded together with the trumpets other than at the actual site of the Temple, since the relevant passage in Psalms indicates that both instruments are employed simultaneously only "before the King, God." Rabbi Frank maintains that while the entire city of Jerusalem is "before God," nevertheless the site of divine kingship is limited to the Temple Mount proper. Hence the rest of Jerusalem is not "before the King, God." Therefore, argues Rabbi Frank, trumpets unaccompanied by the shofar must be sounded in Jerusalem in the event of impending misfortune.
