Kaikhosru Shapurji Sorabji (1892-1988) was an English composer-pianist of Parsi descent. Although he composed many works for piano, these compositions remain largely unknown to the public due to the composer's self-imposed 40-year ban on public performances of all his works and the immense technical difficulty of his music. This research proposes a comparative study of Sorabji's two versions of Rapsodie espagnole de Maurice Ravel-Transcription de concert pour piano (1923, 1945). These transcriptions are based on Ravel's orchestral work and are different in terms of the style of their arrangements: the 1923 version is more of a literal transcription, whereas the 1945 version has been expanded upon the former. This dissertation compares the differences between the two versions, as well as identifying how Sorabji infused his own style into the 1945 transcription. This study relies on primary sources including writings and manuscripts of Sorabji, and secondary sources such as articles on interpreting Sorabji's piano works and biographies about Sorabji.
