I do not see the command to use repetitive chants there at all. Try again.

I was editting my last post to explain as you wrote this.
The book of Psalms was divided into 2 parts "psalms" and 'hymns'. Psalms were sung corporately, hymns were sung responsorially.
If you don't agree with that... just look at Psalm 136
Psalms 136:1-9 1 O give thanks unto the LORD; for he is good:
for his mercy endureth for ever.
2 O give thanks unto the God of gods:
for his mercy endureth for ever.
3 O give thanks to the Lord of lords:
for his mercy endureth for ever.
4 To him who alone doeth great wonders:
for his mercy endureth for ever.
5 To him that by wisdom made the heavens:
for his mercy endureth for ever.
6 To him that stretched out the earth above the waters:
for his mercy endureth for ever.
7 To him that made great lights:
for his mercy endureth for ever:
8 The sun to rule
F366 by day:
for his mercy endureth for ever:
9 The moon and stars to rule by night:
for his mercy endureth for ever.
It should be obvious this Psalm was sung responsorially (as many were). This was the pattern used by the early church.
