More aesthetics in the Bible, from passages that I had never noticed before: Psalm 101, identified as “a Psalm of David,” reflects specifically on singing and making music. It begins:
I will sing of steadfast love and justice;
to you, O Lord, I will make music.
Elsewhere, David also refers to singing and making melody “to the Lord” (Psalm 27:6; see these other places). So the Lord is the audience of the music. The artist is addressing not other human beings but God Himself.
