How Bright These Glorious Spirits Shine is a hymn by Isaac Watts, based on Revelation, with music by John Bacchus Dykes. This is a hymn resetting for four-part (and, later, five-part) choir, to be used either as a stand-alone anthem or for congregational singing. Every one of Watts' seven (short) verses is here, each with its own treatment. The first verse presents the tune in unison, for both choir and organ, after a verse-long introduction. The second verse is in Dykes' original harmonization, including added notes for the organ. A brief transition move the key from F to G, where in the third verse the choir repeats Dykes' harmonies with an organ solo over top them. The altos and tenors take the lead for the fourth verse, with a delayed soprano descant soaring above them. The fifth verse is present a capella, and is a return to Dykes' four parts. The organ then changes the key to A-flat (the key of the original hymn) for a unison choral treament with a complex organ accompaniment for the sixth verse. The final verse is in five voices, with the melody being passed around by the divided sopranos and the altos. There is a short concluding passage on the organ to finish. As the melody is present in an undecorated form at all times, there's no reason that a congregation wouldn't be able to sing along with this arrangement. The piece itself shouldn't take a great deal of time or effort to learn or perform, and should be usable in any church service where the hymn could be present.
