"As is the case with quite a few of his works, there are two versions of Schumann's opus 14 - a three-movement ''Concert sans Orchestre'' from 1836 and a ''Grande Sonate'' in five movements from 1853. We do not know the reason for the revision the publisher of the first version was, however, delighted he considered the ''idea of the concerto'' to be very up-to-date. Perhaps Schumann later reacted to what the dedicatee Ignaz Moscheles had said that the piece had ''less of the demands of a concerto and more the characteristics of a grand sonata''. In our revised edition, which now also contains the complete early version, the editor Ernst Herttrich provides detailed information on both versions in an extensive preface and commentary.?"
