This movement has a singing yet inventive character, where the theme is continually transformed by variations that require sustaining the melodic line while renewing harmonic colors. You will need to focus on Connaissance des formes (3.6/5) to pinpoint theme entries and structure your dynamics and pacing so each variation reads clearly, and on Pédale de sustain (3.1/5) to manage resonance without blurring inner lines — here the physical task is to anticipate harmonic shifts and time pedal lifts and depressions to match reharmonizations. The piece belongs to the Romantic period and is the second movement of the Piano Sonata No. 2, an important part of Szymanowski’s piano output. I do not provide a recording recommendation because I am not fully certain of a single definitive reference.
