An art song is usually for solo voice and is accompanied by solo piano. (Just as a side note, I recommend listening to the Erlking by Schubert if you have time; it's a German art song (lied))
When the Youth takes the glass of milk and the plate of waffles from the woman at the counter and starts crying in shame, for he is not able to pay for them, represents the climax in <span>"The Glass of Milk".
