What does the title "two kinds" mean? what are there two kinds of? what do those two kinds have to do with the piano pieces "pleading child" and "perfectly contented"

Explanation:

The title "Two Kinds" refers to two types of daughters: the obedient kind and the independent kind. Jing-mei feels that she has disappointed her mother time and time again by being the latter kind and asserting her will again and again against her mother's wishes. Yet at the end of the story, she realizes that the piano piece that she played as a child, "Pleading Child," and the song on the other side, "Perfectly Contented," are actually two halves of the same song. I think that this is the moment that Jing-mei realizes there aren't actually two kinds of daughters, but that every daughter has two halves: the half that longs to please her parents by obeying them and the other half that wants to be herself.
