The second movement of a concerto for Cello and orchestra I wrote a few months ago based on some Appalachian folk songs. The Cello is a bit less present in this part compared to the first...
Here's a list of what's happening in this part:
0:00 Introduction
0:13 First song "Gypsen Davey"
1:28 Second song "The Lady and the Soldier"
2:30 Brief return of the first melody
2:55 Oriental sounding variation of the first melody
3:45 Slow version of the second melody played by the oboe and cello
4:11 Triumphal variation of the first melody
4:35 A fugue begins in the strings based on the first melody interrupted by a strange version of the second melody
5:23 The fugue resumes and builds with material from both melodies overlaid, reaching a climax
6:28 Big return of the first melody
6:54 First and second melody overlaid in two different keys
7:19 Final return of the Gypsen Davey tune and coda.
