Maya Angelou on Reciting Poetry:
At the age of eight, while living with her mother, Angelou was raped by her mother’s boyfriend. She told her brother, who told the rest of their family. The man was found guilty but was jailed for only one day. Four days later, he was murdered. Angelou became mute for almost five years, believing that “I thought, my voice killed him; I killed that man, because I told his name. And then I thought I would never speak again, because my voice would kill anyone…” During this period of silence she developed her extraordinary memory, her love for books and literature, and her ability to listen and observe the world around her. Angelou and her brother were sent back to their grandmother. She credits a teacher, Mrs. Bertha Flowers, with helping her speak again:
You Do Not Love Poetry
When I was about 11 and a half, she said to me one day
— I used to carry a tablet around on which I wrote answers — and she asked me, “Do you love poetry?” I wrote yes…She told me, “You do not love poetry. You will never love it until you speak it. Until it comes across your tongue, through your teeth, over your lips, you will never love poetry.”…Finally, I did take a book of poetry, and I went under the house and tried to speak, and could.

Robert Bly on reciting poetry:
Reciting political poems at Vietnam gatherings, I experienced for the first time in my life the power of spoken or oral poetry. A briefly lasting community springs to life in front of the voice, like a flower opening — it can be a community either of excitement or of feeling. The community flowers when the poem is spoken in the ancient way—that is, with full sound, with conviction, and with the knowledge that the emotions are not private to the person speaking them.
