FOR BRASS QUINTET, TIMP, AND ORGAN
Arranged for String quartet, French Horn, Oboe, Timp with Congregation, Choir, and Organ.
The form of descant sung today, a soprano countermelody above a congregational hymn tune, emerged and grew rapidly following the introduction of the 1906 English Hymnal, which some consider the music editor's (Ralph Vaughan Williams) magnum opus (he might not agree). The volume's majestic arrangements include obscure and forgotten tunes curated by Vaughan Williams, along with familiar tunes improved by his harmonizations, and a few original tunes. These arrangements invited such treatment, as merely adding a desultory, plagal 'amen' seemed insufficient homage to this new standard of composition.
As you might expect, however, the practice and use of the descant had an earlier form, as the term itself implies: descant - 'against the song,' from dis-, a Latin cognate implying opposition, and from cantus, 'song;' a word that lives today as the word chant. In its early practice, it was often extemporized, and frequently sung in a different style or rhythm, the high voice at triple tempo, hence the alternate name of the soprano voice, treble.
