The Final Psalm
David concludes the Book by saying that G-d should be praised by the angels in the highest levels of holiness, as well as in the firmament, which is where we interface with Him. He should be praised for His mastery over nature and the miracles He has wrought for Israel by changing nature. He should be praised with every type of instrument, from the blasts of the shofar to harps, tambourines, flutes, cymbals, and more. (David lists nine types of instruments in all - even castanets!) A person's entire soul should be dedicated towards one goal: praising G-d!
What an appropriate note upon which to conclude.
