I happen to stumble across this chapter in the House on Mango Street. I found it very interesting that Cisneros used this type of formatting. The chapter starts on with song lyrics assuming that Lucy is the one that is singing it. The song lyrics then proceeds to a rhyme and a repition in the next paragraph. It makes the chapter flow well between the singing and the dialogue. Cisneros uses this format and language technique because it introduces the fact that Esperanza herself is actually singing and dancing within this chapter.
