Here’s an intergenerational setting of Psalm 100 written by Carolyn Brown. It’s set for one leader and two groups. Brown suggests that the two groups could be choir and congregation or two halves of the congregation.
Psalm 100
Leader: Make a joyful noise to the Lord, all the earth.
Group 1: Worship the Lord with gladness!
Group 2: Come into God’s presence with singing!
Leader: Know this! The Lord is God.
Group 1: Know this! We belong to the Lord who made us.
Group 2: Know this! We are God’s people,
and the sheep of God’s pasture.
Leader: So, enter God’s gates with thanksgiving,
Group 1: Come into the holy courts with praise.
Group 2: Give thanks to God and bless God’s holy name.
Leader: For the Lord is good;
Group 1: God’s steadfast love endures forever,
Group 2: God’s faithfulness is for all generations.
