Page "Opus number" Paragraph 5

Other examples of composers ' historically-inconsistent opus number usages include the cases of César Franck ( 1822 – 1890 ) and Béla Bartók ( 1881 – 1945 ) who initially enumerated, but then discontinued enumerating, their compositions.

Carl Nielsen ( 1865 – 1931 ) and Paul Hindemith ( 1895 – 1963 ) were also inconsistent in their approaches.

Moreover, Sergei Prokofiev ( 1891 – 1953 ) was a consistent enumerator who assigned an opus number to a composition before composing it ; at his death he left fragmentary and planned — but numbered — works.

In revising a composition, Prokofiev occasionally assigned a new opus number to the revision, thus: Symphony No. 4 is two thematically-related but discrete works: ( i ) Symphony No. 4, Op.

47, and ( ii ) Symphony No. 4, Op.

112 ; the former, Op.

47, was written in 1929 ; the latter, Op.

112, is a large-scale revision written in 1947.

Like-wise, depending upon the edition, the original version of Piano Sonata No. 5 in C major, is twice catalogued as: ( I ) Piano Sonata No. 5, Op.

38, and as ( II ) Piano Sonata No. 5, Op.

135.
