In 1949 and 1950, trumpeter Miles Davis organized recording sessions of a nine piece group in New York which has been referred to as the Miles Davis Nonet or the "Birth of the Cool." The main idea of the group, led by Davis, was to present a more subdued and lighter sound in contrast to the bebop style of Charlie Parker and Gillispie. To do this, Davis got musicians that complimented this type of style like: saxophonists Lee Konitz and Gerry Mulligan who both employed lightweight and airy tone qualities. To accentuate this style, Davis contributed his signature trumprt sound by playing with a special "harmon" mute on his trumpet. Along with the above musicians and a rhythm section, Davis added french horns, trombones and tuba to complete this harmonic texture of the cool jazz sound. Other musicians of the cool jazz sound also include pianist, Paul Desmond and saxophonist, Dave Brubeck, known as the Dave Brubeck Quartet. click on the pictures below to hear examples
