How do you change a major scale into a jazz scale?

I know the second step is to find the pentatonic of that scale but whats next? If have another way to find the jazz scale you are more than welcome to explain that way. Thank you for answering!How do you change a major scale into a jazz scale?
';Jazz scale'; is the mixolydian mode or dominant 7 scale. You simply play a major scale with a b7. ie: C D E F G A Bb C (in C)



The scale based on minor pentatonic is the ';blues scale';. A blues scale from the major is 1, b3, 4, #4/b5, 5, b7, 8 ie: C Eb F Gb G Bb C (in C) The blues scale isn't really a pentatonic (pentatonic means ';5 notes';), it's hexatonic and if you add in the natural 3 it's heptatonic.



Jazz uses a lot of modal scales though besides just these. There are all sorts of cool scales you can improvise around. Learning all of the blues scales is a good start but don't stop there. Check out the modal scales too - the major and minor pentatonics are pretty useful to know.How do you change a major scale into a jazz scale?
I'm pretty sure there's no such thing as a ';jazz scale';. I'm in a college jazz class and scales change depending on the chords that are played. But usually you want to play dominant 7ths. So just whatever 7th chord you're playing, lower the 7th by a half-step.
All scales are potentially ';jazz scales'; if you swing them. A bebop scale may be what you're looking for. All you do is add the chromatic passing tone between 5 and 6.



In C: C D E F G G# A B C
there is such a thing as a jazz minor scale. these scales are used to improvise over any minor #7 chords but can also be used over other chords. you should look jazz minor scales up. also call Melodic Minor Scale.



hope i was able to help
a common ';jazz'; scale is (in c) is

c eflat f gflat g bflat c

or

M1 m3 P4 m5 P5 m7 P8

that's actually a blues scale but that may have been what you meant.
Check out the diminished scale...there are three... for c, eb,gb,a...use c,db,eb,e,gb,g,a,Bb...Or try the diminished-wholetone scale.....c,db,eb,e,f#,g#,a#...The form for the diminished scale is half step, wholestep, half step, whole step, half step, whole step, half step, whole step....This scale works very well over dominant seventh chords...Ther are only three different scales to learn....built on ';c'; ,';db';, d,... the one on ';c'; covers c,eb,gb,a...the one on Db covers db,e,g,Bb....the one on D covers d, f ab, and b...A good plan is to think of II, V progressions and start on the root of the II chord and progress thru the V chord...IE: D-7, G7..use d,e,f,g,ab, Bb, b,db,d....Hope this helps you out.
