A descending scale in thirds on weak beats serves as a unifying element throughout the piece. Fluid harmonic changes characterize the work, such as modulations observed in the first half up to the perfect cadence in m. 23 that establishes the dominant key, in a series of sequences in the latter half, and the frequent use of suspensions and appoggiaturas after the target key is established. Formal construction methods, such as leading to a subsequent sequence by slightly altering the motive of a preceding sequence (e.g., m. 17) and starting the next section with the resolution of the leading tone (m. 23), also contribute to its fluid character.
