Composed in 1913. The fluctuating tempo, indicated as 'rubato,' and the structure, where harmonies and arpeggios sharply alternate, recall an improvisatory cadenza in a concerto. Upon examining the score, the harmonies featuring parallel fifths evoke Impressionism, and some scholars point out similarities to Scriabin's approach to harmonic language. However, besides the instruction 'senza pedale' (without pedal), when one actually hears the sound, it is constructed to further emphasize cross-relations and the collision of dissonant intervals, suggesting an intentional awkwardness.
