Coleman Hawkins was taught piano from the age of five by his mother, a schoolteacher who played organ. He took up cello at about the age of seven, then requested a tenor saxophone, which he received on his ninth birthday. By the time he was 12 he was performing professionally at school dances. He went to high school in Chicago, then (by his own account) attended Washburn College in Topeka, Kansas, for about two years, during which time he studied harmony and composition.
