This first movement has an extremely optimistic tendency. Please consider this first movement as a dialogue between two singers. This could be a female and a male, or a soprano and an alto female. In any case, define the two characters. For clarity, let's designate them as female and male for now.

For example, if the female starts from measure 1, the male begins singing the same melody at measure 9. When the female begins a new melody at measure 19, the male starts singing the same melody from measure 27. When the female begins a new melody from the second beat of measure 41, the male starts singing the same melody from the second beat of measure 49. Thus, although the entries are quite delayed, the pattern of female followed by male is fixed and continues until the end of this first movement.

Assume, for example, that from measures 89-91, the female sings C B A G F E C# D C B, extracting only the first note of each beat, and then the male sings the same melody from measures 92-94. Consider measures 99-102 as the orchestral accompaniment.

This is merely an example, but in this manner, set the roles for each singer and the orchestral parts, and perform, attempting to bring out the individuality of each singer (as if sung by persons with different vocal qualities).
