This voluntary is unusual, as it consists of 12 (!) movements and lasts 20 minutes. It is like an instruction that introduces us to most types of voluntary movements. The score is published by Universal Edition (UE 18603).
From the preface by David Byers:
John Christopher Pepusch (1667-1752) was born in Berlin and spent the first part of his professional life as a court musician before he left Germany, apparently because he witnessed an execution without trial. He travelled to Holland and then, during the first few years of the 18th century, settled in London just as Handel was to do a few years later.
Before long Pepusch had established a reputation as a keyboard player and composer. In 1713 he was awarded his D. Mus. at Oxford and in 1715/16 he wrote an important series of masques for the Drury Lane Theatre. Shortly after this he was appointed music director to James Brydges (later Duke of Chandos) at Cannons where Handel was composer-in-residence 1717/18.
In 1728 Pepusch supplied continuo parts and an overture for The Beggar’s Opera which enjoyed a considerable success although its sequel, Polly, was banned for many years. At about this time, he gave up composition and devoted the rest of his life to teaching (his many pupils included William Boyce and J.H.Roman) and the study of “ancient music” (his extensive collection of books included the Fitzwilliam Virginal Book).
He published a Treatise on Harmony in 1730/31 and edited Corelli’s Sonatas and Concertos for publication in 1732.
In 1737 he was appointed organist of the Charterhouse and there he remained until his death at the age of 85 “… highly esteemed, above 50 years distinguished as a most learned Master and Patron of his Profession”.
