F-sharp major, 2/4 time. This piece is characterized by the resonance of the black keys. The initial eighth notes on the black keys should be played with a bouncing quality while maintaining resonance. In measures 6 and 7, use the pedal to differentiate between accents and tenuto, striving for careful tone production even at mf without becoming overly strong. The descending chords here have a particularly beautiful resonance. From measure 9, the same note is repeated three times while ritardando, and from measure 13, the initial melody reappears. For the final sub.sff chord, it is advisable to carefully build the sound, valuing its resonance so that it does not become harsh.
