The history of the guitar in the jazz starts at the end of the decade of with Charlie Christian that, in only two years, revolutionized completely the interpretation of the instrument. Nevertheless, the guitar, together with the banjo, has in the jazz a tradition much longer than most of other instruments. Long before Christian, already it was a rhythmic instrument and of harmonic accompaniment used by the singers of blues and of work songs, the music of the slaves in the labor camps. It was with Johnny St. Cyr and Lonnie Johnson who gave beginning the history of the guitar in the strict sense of jazz, marking this way the beginning of two traditions of interpretation that last even today: the rhythmic interpretation and of harmonic accompaniment and the soloist, of lines and monophonic phrasings. Bud Scott, Danny Barker or Everett Barksdale were early representatives of the rhythmic style, followed by Freddie Green musicians’ predecessor of the ambience of the jazz rock, of the soul and of the funk, like Cornell Dupree. Teddy Bunn and Al Casey were other guitarists of New Orleans, who tried to unify the traditions inicadas for St. Cyr and for Johnson. In this line, and inside the style Chicago, Eddie Lang and Eddie Condon stood out especially.
