Is this a blues chord progression

[dwest2419]

Hi guys back with another thread. For some strange reason I cant tell what key these chords are in. Here are the chords B7 E9 F#9 and resolving back to B7. I played a B major pentatonic lick over the chord progression.

Thank you for viewing my thread

Edit: Okay, I just thought about something. I know I'm still a beginner or so. But do you know how the major scale is constructed, right? Intervals R 2 3 5 6 but for some strange reason I altered this scale by adding a b3 in the scale and now the scale looks like R 2 b3 3 5 6.  The traditional Major pentatonic scale would be B(Root) C#(2nd) D#(3rd) F#(5th) G#(6th) But now when ascending I have written it like this B(Root) G#(6th) F#(5th) D#(3rd) D(b3) (C#)2nd B(Root)

For guitar players the pattern is along with the B7 chord

E-7-4--------------7
B------7-4---------7
G-----------7-6-4/8
D-------------------7
A-------------------9
E-------------------7

This way it makes the scale sounds bluesy. But yes this is my chord progression a B7 - E9 - F#9 and to voice a chord on the b3 in the key of B a G9. And also for some strange reason it is strange having a dominant chord listed and voiced like it is acting as the "I" chord but it sounds good though. Also for some strange reason - Is it true guys that you can replace the tonic  "I" major chord with a dominant chord?

Thank you for viewing my thread. Please feel free to comment or two.

What we have here.....is a basic I7-IV7-V7 chord progression which is a blues standard.  If you want to really get a bluesy feel, try playing a B (per your example) pentatonic minor or B blues scale over the progression.  You can also experiment with a B Mixolydian or B Dorian scale.  The progression, BTW, is based on blues major but one of the hallmarks of the blues is that it deviates from the rules of normal diatonic harmony in that you can play dominant 7th chords in places where they technically don't belong and the use of minor scale melodies over major tonal harmonies.

Sorry; I meant to say B major.
