The 1935 manuscript comprises a complete piano score with annotations for orchestration covering Nos. 1-51. The orchestration of these numbers, along with the tragic ending, was realized by Prokofiev's assistant Pavel Lamm. The restoration of the original version of the score relies on this orchestration were possible. For Nos. 52-56 Prokofiev did not complete the orchestration; the manuscript contains only a few indications for orchestration. In 1939-40, Prokofiev converted No. 56, the final number of the original score, into "Romeo's Variation," No. 20 of the present-day score. Lamm orchestrated it based on his instructions. In 1944, Prokofiev used Nos. 53-54 in the Second Movement of his Fifth Symphony. Once again, Lamm orchestrated it according to the composer's instructions.
The orchestration of Nos. 52-56 of the ballet was realized by composer Greg Spears in consultation with Simon Morrison based on Prokofiev's models provided by No. 20 of the present-day score, the Fifth Symphony Scherzo, other passages in the ballet using the same melodies, harmonies, and rhythms, and Prokofiev's indications for scoring in the manuscript of Nos. 52-56. Nos. 23, 48, and the second half of No. 25 were realized based solely on Prokofiev's annotations in the manuscript. Nos. 17-18, the "balcony scene," was rescored based on the 1938 suite from the ballet published under Prokofiev's direct supervision.
