Evans, Mulligan and Davis

Whereas in some bands there was a very clear musical separation between the trumpets, trombones and saxophones,Gil Evans preferred the density and the richness obtained by fusing their varied tones in his arrangements. His orchestrations evoke the shimmer of colors and weight of fabrics.The seduction of the sounds took precedence, and his 'Moon Dreams' stretched itself out in dramatic torpor.

Among the other arrangers Miles Davis worked with for the occasion, all of them regulars at Gil Evans room, baritone sax player Gerry Mulligan was particularly innovative: he made deliberate efforts to break with the traditional eight measure form.When the harmonic structure still revered to this convention, he would shift his orchestration to the theme of 'Jeru' he called the sovereignty of the four-beat measure and rhythmic unity into question with isolated two- and three-beat measures.

Miles Davis nonet went against all the then current ideas about the lightweight quality of jazz. It seemed to demand the kind of listening one would expect Carnegie Hall, not a noisy club.

The alto sax player Lee Konitz, one of the principal soloists Miles Davis invited to the 1949 Capitol Records sessions, seemed an unlikely candidate for major role. He was to the bebop saxophone what Woody Allen is to American cinema: he had the pallor of an absentminded student, in sharp contrast to the exuberant faces of bebop. The same was true of his playing. He softened the aggressive virtuosity of Charlie Parker through the influence of the floating phrases of Lester Young and the pianist Lennie Tristano.

Tristano contributed a theoretical foundation to bop musicians discoveries and spread their ideas through his teaching. Emphasizing melody, harmony and rhythm, he streamlined bop's expressionistic aspects. The coterie of young white musicians he assembles, particularly sax players Lee Konitz and Warne Marsh, tempered bop's dazzling language by adopting airy resonances and vibratoless tones. Referring to the fugue and counterpoints of Johann Sebastian Bach, these musicians loved to do two part improvisations and, with Lennie Tristano, were responsible for the first free improvisations (without any written theme or even any agreed upon harmonic pattern).

And The Cool is Born

Cool mean fresh and refreshing but also, of course, relaxed. To someone who is getting upset, you say, 'Keep Cool'. In the late 1940s white jazz musicians began to interpret Charlie Parker's jazz in a new, 'cool' way - and the name stuck. But, paradoxically, the beginnings of cool are attributed to the boldest of the black musicians, Miles Davis.
Indeed, his 1949 recordings for Capitol Records are so significant in this regard that later reissues were grouped under the title Birth Of The Cool.

Compared to Dizzy Gillespie, the other all-star trumpet player of the period, Miles Davis lacked both virtuosity and a brilliant tone. Yes he created a sober, airy, reflective style all his own, featuring a quiet resonance, avoiding high notes and favouring the medium register. 'Keep cool!' he seemed to say to Dizzy Gillespie's velocity, mimicking the message Lester Young seemed to convey to the impetuous Coleman Hawkins. But he was not satisfied with the rapid unison phrases and the unbridled solos that characterized bebop.

In 1948, when Davis formed an ensemble, he tried something new, instead of the usual bebop quintet, he formed a nine-piece band, a nonet.

And there he called on arrangers Gil Evans and Gerry Mulligan. The band featured Davis' trumpet - along with two saxophones, a trombone, a rhythm section, and two instruments rarely used in jazz until then, a French horn and a tuba. (The tuba had been used in rhythm section of the first jazz ensembles in New Orleans, but had been largely replaced by the string bass by this time.)

How It Become Bebop (opening)

Evolved in part from spirituals sung by slaves, jazz is the only truly American musical form. It was created by blacks, for blacks. For years, it was considered to be mere entertainment, but with the advent of bebop in the 1940s, young jazz musicians joined the avant-garde: bop opened the door to modern jazz, the privileged expression of a growing number of artists, strangers to its origins.

In the small clubs of Manhattan's 52nd Street, small experimental bebop groups revolutionized jazz. At the time, New York was the capital of the artistic avant-garde , of intellectual excitement. Literature, theater and painting were being enthusiastically discussed in the city's living rooms.

However, the arranger Gil Evans, recently arrived in New York to rally for the cause of bebop, did not have a living room. One simple room near 52nd Street was enough for him, and it attached a crowd, day and night. The leaders of black music gathered around a turntable there, playing recordings of sax players Lester young and Charlie Parker as well as such European composers as Alban Berg and Maurice Ravel. They met in that room to listen and to talk with each other - and with young white musicians as well.

By the 1940s jazz was no longer the exclusive property of the African-American community. Bop made jazz into a language accessible to all musicians and music lovers in search of a well-informed mode of expression that was free and more physical than Western classical music.
