Although there has been speculation about earlier works, Sorabji's earliest known (albeit lost) composition is a transcription dating from 1914 of Delius's In a Summer Garden [REF].
Various people have stated that Sorabji achieved compositional maturity with Three Pastiches for Piano (1922) and Le jardin parfumé: Poem for Piano Solo (1923),[REF] or with only the latter,[REF] but Sorabji himself regarded his First Organ Symphony (1924) as his first mature work.
