Decent musicology description of this section.
” a lyrical melody sings over the rhythmic ostinato, and the first section is repeated before moving to more in-depth musical development (a characteristic of Classical-era music known as sonata form). The beautiful melody returns at 1:17, this time more serious before an exploding return to the original joyous tone.”

Shame about musicology notes is they usually focus on broad structural elements and mood while giving the main “musical idea” – which is the whole point of the thing – nothing much more than:
“lyrical melody”
“beautiful melody”
Still, structure has its place. Familiarity and all.

Point is, “mathematical melody” is apt but its a point often missed by musicologists but you with your training and interest will pick up on.

wait nvm “rhythmic ostinato” says it. Rhythmic = mathematical.
