Miles Dewey Davis was born on May 26, 1926, to an affluent African American family in Alton, Illinois. His father, Dr. Miles Henry Davis, was a dentist. In 1927 the family moved to East St. Louis, Illinois. They also owned a substantial ranch in northern Arkansas, where Davis learned to ride horses as a boy. Davis' mother, Cleota Mae (Henry) Davis, wanted her son to learn the piano; she was a capable blues pianist but kept this fact hidden from her son. His musical studies began at 13, when his father gave him a trumpet and arranged lessons with local musician Elwood Buchanan. Davis later suggested that his father's instrument choice was made largely to irk his wife, who disliked the trumpet's sound.
Against the fashion of the time, Buchanan stressed the importance of playing without vibrato; he was reported to have slapped Davis' knuckles every time he started using heavy vibrato. Davis would carry his clear signature tone throughout his career. He once remarked on its importance to him, saying, "I prefer a round sound with no attitude in it, like a round voice with not too much tremolo and not too much bass. Just right in the middle. If I can’t get that sound I can’t play anything." Clark Terry was another important early influence. By age 16, Davis was a member of the music society and playing professionally when not at school.
At 17, he spent a year playing in Eddie Randle's band, the Blue Devils. During this time, Sonny Stitt tried to persuade him to join the Tiny Bradshaw band, then passing through town, but Davis' mother insisted that he finish his final year of high school. In 1944, the Billy Eckstine band visited East St. Louis. Dizzy Gillespie and Charlie Parker were members of the band, and Davis was brought in on third trumpet for a couple of weeks because the regular player, Buddy Anderson, was out sick. Even after this experience, once Eckstine's band left town, Davis' parents were still keen for him to continue formal academic studies.
