 Between July 1927 and February 1928 the rules of entry were modified several times to allow the submission of original works rather than a completion of Schubert, and also to permit the use, if prospective completers wished, of Schubert's own sketches for the third movement of the "Unfinished".Those composers who wished to submit a completion of Schubert's work were to use an orchestra no larger than that already employed in the existing movements of the "Unfinished".As far as the submission of individual works was concerned, in October 1927 the organizers stipulated that these should be 'in two movements, composed in the Romantic spirit that animates Schubert's music'.
