Ralph Vaughan Williams's Concerto for Bass Tuba and Orchestra was composed in 1953-4 to mark the 50th anniversary of the formation of the LSO and was written for the orchestra's principal tuba player, Philip Catelinet. It was the first major concerto to be written for the instrument, and remains today the outstanding work of its kind. This new edition is based on all extant sources and contains full textual notes and a discussion of the editorial method. Notable additions are the inclusion of two sets of phrasing for the Romanza-one from the first publication, largely influenced by Catelinet, and the other from Vaughan Williams's manuscript-and the original cadenza to the first movement. The arrangement for tuba and piano has been updated in light of the research carried out by David Matthews, and all orchestral parts have been revised.
