The jubilant text of this hymn demands an assertive, commanding registrational approach. The largest solo reed on the organ should serve as the basis for the solo. If the organ's largest single reed is not enough to lead the congregation, then use a reed chorus: reeds 8' and 16', 8' and 4', or all three pitches. Use the support of a principal chorus, including the chorus mixture, if needed.
The accompaniment should be large enough to support both congregation and solo line, yet allow the solo line to prevail. It is usually best to avoid the use of reeds in the accompaniment when reed tone is the basis of the solo.
