Yellowstone Choral was inspired by the marvellous landscapes of the Yellowstone National Park in the United States. The choral comprises three choral phrases that alternate throughout the work. The beginning is lightly orchestrated, with an oboe solo, but more instruments gradually join in before the second phrase of the choral is introduced. The third phrase does not appear so quickly and when it does it is introduced by horns and trombones before building up to the climax of the choral, where the trumpet takes the upper hand.
After this the choral gradually fades away, with the first and second phrases appearing just a few more times. The choral ends as it began, with a slowly ebbing orchestration.
