The name DEISS 100 was assigned by the editor of the Psalter Hymnal. Like virtually all of Deiss's music, this tune is intended for responsorial singing involving a cantor on the stanzas and everyone on the refrain. The whole song should be sung without pauses between the refrain and the stanzas. Because the rhythm never stops long enough for a good breath, it is best not to have the congregation sing it entirely. Choose choir or a soloist for the stanzas with everyone on the refrain. Groups within the congregation could sing the entire psalm antiphonally, but then sing the refrain in parts and the stanzas in unison. The refrain will need strong accompaniment, possibly with brass instruments; the stanzas can take a lighter accompaniment. Hand clapping and handbells also fit well with this ancient Hebrew "cheering" song. This is jubilant music-keep the energy and rhythms going!
