This eucharistic response was written by John Bell as part of the St. Bride setting, a set of paperless service responses incorporating call and echo learning to encourage community participation. 

The echo comes quickly in several moments and it can feel as if the assembly is 'interrupting' the leader. Practice the response quickly before worship and encourage the community to trust your gestures, even if they seem to be too soon. The overlapping parts generate terrific energy and the confidence of the community will grow as you sing it over several weeks.

And when the first beat of the measure is a rest ("are full of your glory" and the second "Hosanna in the highest"), consider a stomp or clap to remind the assembly of the silence.

The response could sung a cappella or accompanied by a drone instrument (a shruti box or a soft unison or open fifth on the organ) to support the community's voice. 

"Holy, Holy, Holy Lord, (Holy, Holy, Holy Lord)
God of power and might, (God of power and might)
heaven and earth are full (heaven and earth are full)
are full of your glory. (are full of your glory)

Blessed is the one who comes (Blessed is the one who comes)
in the name of the Lord! (in the name of the Lord!) 
Hosanna in the highest! (Hosanna in the highest!)
Hosanna in the highest! (Hosanna in the highest!)"
