I. Allegro Non Troppo (第一乐章 不太快的快板)-Vernon Handley/Royal Liverpool Philharmonic Orchestra/Royal Liverpool Philharmonic Orchestra/Piers Lane

This part is written in sonata form. A six-bar orchestral introduction is followed by a solo piano. This opening remained unchanged in all three versions. In the tempo molto tranquillo, the soloist plays the lyric second subject with the accompaniment of strings and horn. Recent study shows that these two themes reflect the influence of spiritual music which the composer heard in his period in Florida. The development, which starts in tempo quietly, expands by changing its atmosphere with demanding passages for the solo piano. This part does not appear in the final version, where the climax of the second subject is directly connected to the next section.
