Adrian Boult
Forsyth is arguably best known for his "Orchestration", originally published in 1914 and revised in 1935. Dover published a reprint of this revision in 1983 with a new foreword by composer William Bolcom, who lauds especially Forsyth's insight into instrumental culture and his wit. Conductor Adrian Boult recounts in "Adrian Boult on Music" how Forsyth advised Ralph Vaughan Williams about the orchestration of the latter's "A London Symphony".
