IVERSON is a simple chorus; its original melody line was altered in 1929 (see above). Southern Baptist leader Baylus B. McKinney wrote the harmony, which was published in his Songs of Victory (1937).

Sing in harmony unaccompanied or accompany with organ or guitars. When used as a frame around prayers (see Liturgical Use), accompany the first line of each stanza, and then allow the singing to proceed unaccompanied.
