List of compositions by Percy Pitt
Although most of Percy Pitt's compositions seem to have been performed during his lifetime, not everything was published; and not every published work received an opus number. Many of his works were published by Augener, who also published Bridge, Delius and Ireland. A partial list of Pitt's published compositions (both with and without opus numbers) appears in  (34 volumes, published between 1904 and 1910). Some works appear to have been given an opus number after the volume was published some time before 1910. However, gaps still apparently remain in the sequence of opus numbers, e.g. Op. 2, 7, 12, 13 etc. Nevertheless, the opus numbers seem to have been chronologically assigned in approximate composition order.

A number of works exist both in versions for orchestra and for piano reduction (solo or duet), and the dates assigned to many of the entries in this incomplete list should be treated with caution.

According to his own introduction in Pitt's biography, Henry Wood gave the first performances of most of Pitt's major works after 1896 except the G minor Sinfonietta which was written at the request of Hans Richter, who conducted it at the 1906 Birmingham Triennial Music Festival.
