David's psalm of thanks

1 Chronicles 16:7-36 - That day David first committed to Asaph and his associates this psalm of thanks to the LORD:

Give thanks to the LORD, call on his name;
make known among the nations what he has done.

Sing to him, sing praise to him;
tell of all his wonderful acts.

Glory in his holy name;
let the hearts of those who seek the LORD rejoice.

Look to the LORD and his strength;
seek his face always.

Remember the wonders he has done,
his miracles, and the judgments he pronounced,

O descendants of Israel his servant,
O sons of Jacob, his chosen ones.

He is the LORD our God;
his judgments are in all the earth.

He remembers his covenant forever,
the word he commanded, for a thousand generations,
the covenant he made with Abraham,
the oath he swore to Isaac.

He confirmed it to Jacob as a decree,
to Israel as an everlasting covenant:
"To you I will give the land of Canaan
as the portion you will inherit."

When they were but few in number,
few indeed, and strangers in it,
they wandered from nation to nation,
from one kingdom to another.

He allowed no man to oppress them;
for their sake he rebuked kings:
"Do not touch my anointed ones;
do my prophets no harm."

Sing to the LORD, all the earth;
proclaim his salvation day after day.

Declare his glory among the nations,
his marvelous deeds among all peoples.

For great is the LORD and most worthy of praise;
he is to be feared above all gods.

For all the gods of the nations are idols,
but the LORD made the heavens.

Splendor and majesty are before him;
strength and joy in his dwelling place.

Ascribe to the LORD, O families of nations,
ascribe to the LORD glory and strength,
ascribe to the LORD the glory due his name.

Bring an offering and come before him;
worship the LORD in the splendor of his holiness.

Tremble before him, all the earth!
The world is firmly established; it cannot be moved.

Let the heavens rejoice, let the earth be glad;
let them say among the nations, "The LORD reigns!"

Let the sea resound, and all that is in it;
let the fields be jubilant, and everything in them!

Then the trees of the forest will sing,
they will sing for joy before the LORD,
for he comes to judge the earth.

Give thanks to the LORD, for he is good;
his love endures forever.

Cry out, "Save us, O God our Savior;
gather us and deliver us from the nations,
that we may give thanks to your holy name,
that we may glory in your praise."

Praise be to the LORD, the God of Israel,
from everlasting to everlasting.

Then all the people said "Amen" and "Praise the LORD."

I wonder if David wrote this psalm the same day he gave it to Asaph or if he had it prepared beforehand. I wonder how long it took to write it. Did he collaborate with anyone on it?

I wonder if he provided the music to go with it. Or was that Asaph's job -- to compose a tune for it?

It must have been read aloud or sung that day because the people all responded to it. Did David himself read/sing it? Had a soloist or choir rehearsed it so it could be presented to the audience that day?

I wonder if any lyres, harps, cymbals, and trumpets were used to accompany this psalm. Did they rehearse too or did they improvise?

I tend to think this was all planned and rehearsed well ahead of time, but I wonder if anyone ever performed what we might call a jazz psalm where the music was improv.
