This is a clever and effective anthem. A lively setting of George Herbert’s words, alternating 6/8 and 3/4 in effect (although notated throughout in 3/4) gradually introduces into the choral texture the hymn tune Gwalchmai to which those words are often sung. For the final verse, the congregation or a small group of singers sings the hymn tune in unison whilst the rest of the choir and organ enjoy pitting themselves against it. And we realize that the music of the first verse was the countermelody to the hymn tune in the final verse: very satisfying!
