The orchestra includes 4 flutes, 3 oboes, 3 clarinets, 2 bassoons, 4 horns, 4 trumpets, 3 trombones, tuba, 5 percussionists, glockenspiel, harp, and strings. "The Piano Concerto is conceived as an alternation of cadences and episodes where the piano is "reverberated" in the orchestra [...] The score shows the importance of the resonance, the support, the extensions, the echoes, in short of this role of mirror and multiplication played by the orchestra. The whole work is declined in the most extreme virtuosity, creating an oppressive and frenetic climate, leading to the final dazzle" (Bernard Foccroulle). The manuscript is carefully written in Indian ink on 36-line tracing paper. It is dated at the end "29/8/1978". There are a few corrections by scratching; pages 42 to 49 have been replaced by plates. All measurements are numbered.
