'''Symphony No. 4, Op. 47/112''' is actually two works by Sergei Prokofiev. The first, Op. 47, was written in 1929 and premiered in 1930. The second, Op. 112, is a large-scale revision from 1947. Both of the works share significant musical material with Prokofiev's ballet ''L'enfant Prodigue'' or ''The Prodigal Son''.
The two works are stylistically different, because their respective compositional contexts were different. They are formally different as well, and the instrumentation and scope of the revision is much larger.
Because Prokofiev's Symphony No. 4 is in fact two different works, two different but related examinations are required.
