C major, 2/2 time. The key lies in differentiating between the dotted rhythm in the right hand and the syncopated rhythm in the left hand. In the left-hand syncopation, it is important to note that connecting the notes played on the off-beat reveals a descending stepwise progression (e.g., C-B in m. 1, A-G in m. 2, etc.). Although pedal indications are present, it is required to play legato, paying attention to slurs and ties, and utilizing the effect of finger pedaling.
