The art of transcribing orchestral accompaniments for organ is one of the most difficult problems which organists must face. Although a few will become professional recitalists, most organists will at one time or other have a church position and be required to play oratorios and other large choral compositions which were originally scored for orchestra. Several of the most popular of these works (Handel's Messiah, Saint-Saëns's Christmas Oratorio, Fauŕe's Requiem) have already been arranged for organ, but the majority are available only in piano reductions. The main body of the paper deals with this latter group of works, for it is here that the most urgent problems exist. However, some of the organ arrangements now available need considerable revision because they try to imitate the whole orchestra and are virtually impossible to play. Therefore, some preliminary comments on already existing transcriptions seem necessary.

Though Poulenc marks choral compositions with metronomic indications, there are problems concerning tempo. The purpose of this paper is to determine guidelines for dealing with choral tempo. Chapter II relates biographical information pertinent to the study. Style Is examined In Chapter III, determining aspects that call tempo marks into question and influence tempo determination. In Chapter IV, the manner in which Poulenc uses tempo indications in the choral works is analysed and the relationship between form and tempo examined. Chapter V records Information bearing upon tempo from Poulenc's collaboration with conductors, as well as examining recordings of Poulenc's music in which he played or with which he expressed approval. Guidelines for determining tempo are stated in Chapter VI.
