From the early 1920s, jazz musicians attempted to make their improvised lines flow more smoothly by connecting scales and scale tones through the use of chromatic passing tones. During that period of time such jazz giants as Charlie Parker, Dizzy Gillespie, Wes Montgomery, Bud Powell, Charles Mingus began adding an extra half step to the different scales and the modes derived from it (i.e., dorian mixolydian, and locrian). This technique has the effect of making the scales rhythmically symmetrical when played in eighth notes, as most lines were at the time. For instance, a major scale played in eighth notes with the extra half step added. This material is widely used not only by bass guitarists, but also by double bassists. Bebop scales is a serious material for improvisations. They are especially good in building WALKING BASS LINES in jazz. You can also see and hear the harmony over which Bebop scale is played. This is who does it well: Jeff Berlin, Richard Bona, Ray Brown, Ron Carter, Stanley Clarke, Nathan East, Matthew Garrison, Eddie Gomez, Charlie Haden, Dave Holland, Anthony Jackson, Alphonso Johnson, Niels-Henning Ørsted Pedersen, Gary Peacock, Miroslav Vitous.
