An analysis of the first theme and the bridge of a sonata classical structure. As before, the A theme that opens the part "andante" of this concerto is divided into two elements: a1 and a2. The feeling that emerges from this musical theme is: melancholy and sadness. This feeling is obtained by the use of the F# minor key, and a slow tempo that reminds us the Johann Sebastian Bach's arias with the presence of many non harmonic notes that create a theme ornamentation, and finally, the use of many grace notes and retardations that give the melody, a great expressiveness. This theme also has a great vocal range, a large gap between the lowest and the highest notes, here: an interval of augmented eleventh. The a2 element is performed by the orchestra, and its dramatic mood including is obtained by a climax on the note "A" played for the first time with a "forte" dynamic and a larger ambitus based on the interval of fourteenth. This a2 element is simpler than a1, but still very expressive, played legato and including four retardations. The transition or "bridge", between the themes A, and B to come, can be divided into two parts: - The first part of five measures long reminds us of the dramatic element A above, because it icludes many ornaments such as the "grupetto" (three times), and a descending chromaticism with regular eighth notes and sixteenth notes. The first element of the bridge is based on a cell that will be repeated three times, in order to free us from the key of F# minor and brings us gradually to a much more serene element in the sixth measure, in the relative key of A major, which prefigures the following B theme. At the end of this second part, we will have a cell of three sixteenth notes repeated 3 times, foreshadowing the cadence that will install the key of A major and the following B theme.
