I recently listened to Leighton's music for strings. The Symphony for Strings, I later read, was a student work and rather dull, though skillfully done. However, I found the "Concerto for String Orchestra" to be very impressive. It is in a sort of slow-fast-slow scheme, with the central movement a scherzo of sorts and the outer movements more extensive in scope. It has some of the strong functional dissonance which seems to be the convention of English String music of the early 20th century. Almost Finzi-esque. I have to start listening to the symphonies again.
