Miles popularized cool through his album, Birth of the Cool, but this is only mistakenly believed to be the start of cool, as it was already being played. “He had a style like the players from St. Louis, singing sound, and he didn't play too many notes or play those real fast tempos” (Davis 1989: 62). From Miles Davis’ autobiography, it is clear that he heard a style that was much slower than the bop he was playing alongside Bird and Dizzy. He much rather preferred this style which became known as cool. Talking to his father about dropping Julliard, he was given invaluable advice to never be like a mockingbird and to have originality in whatever he does in life. Miles Davis is one of the defining giants in the cool era. David Brubeck and Stan Getz also influenced this new style of jazz. Brubeck explored and borrowed ideas from other parts of the world. He integrated new meters, melodic ideas, creating many jazz standards, and one of the top selling jazz albums, Time-Out. Getz popularized bossa nova, yet another jazz genre with many ties with cool. Getz brought in Latin ideas mixed with the more relaxed cool music. Brubeck and Getz epitomize what Herbie Hancock was talking about, borrowing ideas, creating new ones, and sharing.
The differences in ideas can be more clearly seen by a side-by-side comparison. Cool is identified as an easier to follow genre that avoided the loud and aggressive bop style. In
