Evolution

Then jazz became more complex with the arrival of bebop. Tempos are faster, with richer and more complex harmonies. Influential musicians in this style include: Miles Davis, Charlie Parker, Dizzy Gillespie, Thelonious Monk, Bud Powell…

Cool jazz then arrived in the 1940s. With Chet Baker, Miles Davis, Stan Getz, Bill Evans… The term is hard to define because a lot of music has been defined as cool jazz. In any case, the musicians wanted to move away from the virtuosity of bebop by seeking calm and delicate sounds with long, linear and sometimes floating melodies.

In 1950 came the arrival of free jazz. It frees itself from harmonic constraints, and emphasizes a style of free improvisation, favoring the energy produced by the musicians such as : Ornette Coleman, John Coltrane, Archie Shepp, Charles Mingus…

Hard bop appeared in the mid-1950s. It draws its influences from the blues and gospel and insists on saxophone and piano playing, with a large place for rhythm. It is a bit of a return to the roots with jazz groups such as the Jazz Messengers, Art Blakey, Horace Silver, Sonny Rollins…

A few years later, modal jazz appeared, with the invention of all the modes that derive from a major, harmonic, and melodic minor scale. This creates new sounds and atmospheres. Influential jazz musicians include Herbie Hancock, Wayne Shorter, McCoy Tyner…

From 1960 to 1970 came the arrival of jazz fusion, jazz with rock. Saturated sounds but with improvisation, using electronic instruments.

All these jazz styles led to other jazz genres: Latin jazz, Afro-Cuban jazz, West Coast jazz, ska-jazz, avant-garde jazz, indo-jazz, soul jazz, chamber jazz, jazz-funk, loft jazz, jazz punk, acid jazz, jazz rap and many others.
