In some Psalms, music resembles prayer in that all people seem welcome to participate in a direct way. David himself comes from the tribe of Judah. That disqualifies him from officially blowing the silver trumpet, as if he were an Aaronic priest. It also means he should not take the part of a Levitical musician. Yet, in his own capacity, he can play his harp to God. In a Psalm attributed to David, the poet says,
I will sing a new song to You, O God; upon a ten-stringed harp I will play to You. (Psalm 144:9)
Similarly, Psalm 98 invites all people (and all created things) to join in this kind of worship.
Make a joyful noise to the LORD, all the earth; break forth into joyous song and sing praises! Sing praises to the LORD with the lyre, with the lyre and the sound of melody! With trumpets and the sound of the horn make a joyful noise before the King, the LORD! Let the sea roar, and all that fills it; the world and those who dwell in it! Let the rivers clap their hands; let the hills sing for joy together. (Psalm 98:4-8 cf. Psalm 100:1)
