Loud, exuberant vocal praise — the kind that cannot be contained. Frequently calls on creation itself to join: trees, mountains, heavens. This is praise as celebration, not ceremony.
The Psalms use ranan for the spontaneous overflow of joy before God. Isaiah 44 and 55 call on creation to break forth in singing. Joy in God should exceed any earthly joy.
Creation praise (trees, mountains, heavens rejoicing in ranan) prefigures the 'new creation' praise of Revelation where every creature joins the song. Joy in God is cosmological, not merely personal.
