With so much uncertainty in the world, there is one thing we can say with 100% certainty: we will all die. The Unetaneh Tokef prayer reminds us of the scary, but very real fact of our mortality and vulnerability.
The leader loudly chants, "The King," in a distinct, ancient melody, as if announcing the arrival of a government official. In this prayer, God sits upon an "exalted and uplifted throne," but God is said to sit upon other types of thrones as well.
The Zikhronot section of the Mussaf Amidah makes a claim that we are all remembered - ourselves as individuals, as well as our biblical ancestors - and that, even if the Divine sits as King on a lofty throne, every one of us is considered and remembered by God.
The shofar is one sound the Jewish people can identify almost immediately.
