The third piece (Rubato - Tempo Giusto Capriccioso) is written in a three-part form (A-B-A') with an introduction, and its form is the most easily graspable among the three pieces. While a clear melodic line appears in the middle section, in the A and A' sections, the left hand's sixteenth notes moving in a zigzag pattern across a wide range and the right hand's chords appearing at irregular intervals create a tension that disrupts the sense of meter.
