The chapter opens with a description of the bird calls and the songs that are sung by birds. The bird calls carry a specific meaning to those who listen to the song, but recent research shows that they are composed of a hierarchical structure. Listening stamina and skill is gained through practice, effort, and can also be taught to sensibility. The song, however, cannot be learned through action or words. Everything touches is transformed into sound, information, and is impossible to duplicate in mere words. The chapter ends with a soliloquy in which the author says that he has shown his glory on earth, and that he dedicates himself to his father. The hour has come for him to give glory to his son, so that he always thought he would. He says that after today, his son may give his glory to him. He feels that he really likes his daughter and that it is time to wring everything out of him.
