Edelweiss
You can hear the enjoyment Georg gets out of singing again after so long, but you can also see the growing appreciation he has for Maria. Awwwwww squee. (And you also see Baroness Elsa realizing that she has a rival for Georg's affections! Interestingly, Elsa gets no singing roles at all in the film.)
