for me it would be:
Aria: Purple grapes
Adagio: (Kinda hard, but I think I'll go with) Pineapple
Sonata: Long to explain, but here in Argentina there's an ice cream called "Crema del Cielo" (its translation would be like "Sky Cream"), which has a base of "american ice cream" (your regular plain white "ice cream") but with slight notes of vanilla and cherry.
And well, not only is it the same light blue as Sonata, but it's a very popular ice cream among kids (jeez, it was my favorite ice cream even, until I grew up and suddenly forgot), so I think it would suit her perfectly.
