The sonata is written in a post-
Romantic style, similar to Scriabin's other works of the time. The first movement, expressive and calm, is
monothematic (based on a single theme). The second movement, celebratory and climactic, starts
attacca right after the
Andante movement. A more
Romantic idea is the use of
cyclic form in restating the
Andante’s main theme (
dolcissimo) as the ecstatic climax of the
Prestissimo volando movement (
Focosamente,
giubiloso). This outlay appears closely related to the last two movements from the
3rd sonata, also linked by an
attacca, where the climax of the finale likewise restates the lyrical
Andante theme of the third movement. Russian composers such as
Tchaikovsky or
Rachmaninoff often restated the lyric theme of the finale movement as climactic
coda (for example in the
piano concertos). Scriabin instead returns to the 'slow' movement's theme, and this may have led to further experiments with a condensation of form in the single-movement
5th sonata where the climax (
estatico) is again a restatement of the
Languido theme (
dolcissimo). == Background ==
