An Analysis of Beethoven's Rondo in C, Op.51 No.1
Written by Andrew Schartmann
General Remarks
Contrary to the implication of the opus number (51), this rondo was composed early in Beethoven's life, around the same time as the first three piano sonatas, Op.2.[1] It bears a considerable degree of individuality, including a fairly unique approach to rondo form, and affirms that even in his small-scale compositions, Beethoven was pushing the boundaries of previous efforts.
According to traditional letter-name analysis, this work is in five-part rondo form: ABACA. This labeling will only be used to divide the work into sections of manageable size and should not be considered as an accurate description of the form as it ignores the unique features that account for the subsequent formal organization.[2]
Rondo, Op.51 No.1
A - (mm.1-17)
The structure of the main theme (small ternary form) is quite ordinary for a rondo; however, the contrasting middle (mm. 9-13) offers something very unique in that it fails to modulate to the dominant.[3] This lack of tonal variety is quite striking and can only be understood in retrospect. For the time being, it may be assumed that Beethoven was reserving the arrival of a prolonged dominant harmony (within the main theme) for an important passage later on in the work.[4]
Aside from innovative formal structures, Beethoven's music is often characterized by the development of small motives. This developmental procedure is most salient when its germinal subjects are presented in isolation;[5] however, in this rondo, rather than constructing phrases using motivic units, Beethoven extracts characteristic elements from a fully-formed theme and uses them as a basis for new material.
For example, the first of these elements is the syncopated rhythm that appears in mm. 2-3 of the main theme. Its local function is to break up the squareness of the main theme and to initiate rhythmic and harmonic drive toward the cadence. The 7-6 suspension in m. 2 sets off a quickening of the harmonic rhythm and the sixteenth notes become more plentiful as the half cadence (m. 4) is approached. Its global function, however, is more complex. When the syncopated figure becomes the rhythmic basis for the minore section, it provides a non-melodic link to the main theme creating a sense of coherence amidst seemingly unrelated material. This rather distant relationship can be contrasted with one that occurs between two gestures of great proximity earlier on in the work.
