Siman 593

The tekiot do not impede the berakhot, and the berakhot do not impede the tekiot. For example, one who does not have a shofar to blow—nonetheless, he should recite the berakhot of Malkhuyot, Zikhronot, and Shofrot. And similarly, one who does not know the berakhot—nonetheless, he is obligated to blow when he has a shofar. And even though the sages ordained that they should blow according to the order of the berakhot, nonetheless, this is not a requirement that impedes. And this law applies both to Rosh Hashanah and to Yom Kippur of the Jubilee year, which existed during the time of the Mikdash, for then they would blow and recite the berakhot of Malkhuyot, Zikhronot, and Shofrot.

But the blessings of Rosh Hashanah, and of the Yom Kippur of the Jubilee year—obstruct one another, such that if he does not know all of them, he shall not say what he knows of them, but rather he shall say nothing at all. And this is only regarding Malchuyot, Zichronot, and Shofrot, for all of them were instituted specifically as one. However, the rest of the blessings are not subject to this. And similarly, the blessings of the entire year do not obstruct one another, and whichever one he knows, he shall say it (Magen Avraham).

And so too, the tekiot are mutually dependent: for if one knows how to perform a tekiah, but it is not within his power to perform a teruah—he should not perform the tekiah either. However, if he knows how to perform Tashat, and does not know how to perform Tarat, or vice versa—he should perform them, for both this and that are a teruah, according to what the Rosh wrote in the name of the Gaon, as I wrote in the previous siman. And he fulfills the obligation from the Torah. And all the more so, the order of the berakhot and the tekiot are not mutually dependent, and he may prioritize the berakhot before the tekiot, or the tekiot before the berakhot. Nevertheless, ab initio—he should prioritize the tekiot. But the order within the tekiot themselves, or within the berakhot themselves—is indispensable, for if he prioritized a teruah before a tekiah—he has done nothing. And so too, if he prioritized Zikhronot before Malkhuyot, or Shofarot before Zikhronot. And he must return and blow or recite the berakhot according to the order.
