Program Notes:
This concerto is single-movement piece. There are five sections which is organized in ABABA form.

A string introduction starts the piece and is then followed by the rhythmic first A section with a stormy and primitive character. The solo trombone interchanges with the chorus to play the subject, and the strings join in after a climax. The subject in the A section consists of two melodic motives: the first is a minor 2nd, Bb - B natural, while the second is a major 3rd, D - F#. These two ,melodic motivies are magnified by a varied ostinato technique, adding more notes in between the two-note motif each time the motif repeats.

The B section contrasts with the A section by its smooth and melodic character. Varied ostinato is still used here for developing melodic motif. However, notes are added after the two notes motif, rather than added in-between.

Drums as well as metallic percussion instruments on one hand punctuate the melodies in the trombone and chorus parts respectively, while providing colours on the other. By increasing the dynamics and thickening the texture, the piece is pushed towards the second climax, which is soon resolved and leads to the next A section. The materials of this section are developed from those of the first A. A xylophone is added here.

Most materials in the second B section are derived from theifirst B, but are constructed in another tonal area. the second B section develops into its climax near the section end like the first, but instead of resolving, it pushes further to the peak of the whole piece. the final section restates the A section and the whole piece ends by breating yet another climax.
