Cuthbert Harris, Mus.D. (Durham, 1899) (b. Holloway, London, England, June 7th, 1870; d. Gorleston-on-Sea, June 17th, 1932) studied at the London Organ School. He was Organist of St. Andrew’s, Streatham, London, 1893; St. Leonard’s Parish Church, Streatham, London, 1903. He was a teacher and author of “First Studies for the Organ”. b. Holloway, London, England, June 7th, 1870; d. Gorleston-on-Sea, June 17th, 1932.
Best known for his compositions for organ most of which continue in today's organ repetoire. Among his organ works are "Andante sostenuto in F", "At Eventide", "Berceuse in G", "Chanson pastorale", "Concluding Voluntary in D minor", "Concluding Voluntary in G major" (the piece uploaded) and "Festival Postlude in C".
Harris also authored a number of piano method books including two written under the pseudonym Gladys Cumberland; "A Child's Primer In The Elements Of Music" (1924) and "A Short Primer In The Elements Of Music" also in 1924.
The "Minuet and Trio in G" (or the "Concluding Voluntary in G") is a nice piece. It was published by Novello in 1902, and is an excellent example of the musical style of the period. It's heroic, but still light-hearted, and would make an excellent "first piece" if you are thinking about exploring English music of this type.
As a "performance suggestion," I think this will sound best if you stay more or less "in time" between the sections. You can "add a measure" if you have difficulty in changing the registrations, but I personally think it sounds best if you don't. :-)
I found no photos of Cuthbert Harris, but I did add photos of the churches where he served as organist. The score is also attached. :-)
