French organist and composer, Marcel Dupré (1886-1971) is also remembered as a significant pedagogue. However, his prominence within the Organ repertoire remains absolute, with sublime works including his Prelude and Fugue in A flat major.

Dupré studied at the Paris Conservatoire with Louis Vierne and Charles-Marie Widor, where he won prizes for Piano, Organ and fugue, as well as the Grand Prix de Rome. He was a famous Organ virtuoso and was able to perform the entire works composed for the instrument by J. S. Bach from memory. Dupré's Op. 36, No. 2, the Prelude and Fugue in A flat major for Organ was composed in 1938. The score begins with a helpful explanation of signs and abbreviations. The work displays contrast through tonality, rhythm, timbre and harmony, amongst other aspects. Dupré's compositions and didactic works remain important to organists today and his Prelude and Fugue in A flat major, suitable for advanced organists, is no exception.
