Hello all.Could someone please recommend some books or give me the formulas to create natural,harmonic,and melodic blues scales?Does the blues scale come from Pentatonic scales?And if, so could someone also help me with creating pentatonic scales?Thank you.

Wiki can tell you.

C Eb F F# G Bb
1 b3 4 #4 5 b7

C major blues scale (same notes as A minor blues scale)
C D D# E G A
1 2 #2 3 5 6

Thank you.Is there a natural blues scale?If so does anyone use it?What is the most popular blues scale?( Blues:Natural,Harmonic,or melodic).What are the steps for the Blues Natural Scale?What are the notes of a Blues Natural Scale?

The flattened 5th and dominate 7th make it a blues scale. You can play both the flattened 3rd and the 3rd in a standard blues. But the major 3rd will sound like a train wreck in a minor blues progression. As far as I know there is no natural or harmonic blues.

I listed the two blues scales above, the other names you mention are either nonexistent or irrelevant to blues.

Here are some notes for some blues scales I regularly use...Try these out: -

C Blues scale
C - Eb - F - G - Bb – C

F Blues scale
F - Ab - Bb - C - Eb - F

G Blues scale
G - Bb - C - D - F – G

D Blues scale
D - F - G - A - C - D
A Blues scale
A - C - D - E - G – A

E Blues scale
E - G - A - B - D – E

B Blues scale
B - D - E - F# - A - B

F# and Gb Blues scales
F# - A - B - C# - E - F# 
Gb - A - B - Db - E – Gb


Db and C# Blues scales
Db - E - Gb - Ab - B - Db
C# - E - F# - G# - B - C#


Ab Blues scale
Ab - B - Db - Eb - Gb – Ab

Eb Blues scale
Eb - Gb - Ab - Bb - Db – Eb

Bb Blues scale
Bb - Db - Eb - F - Ab - Bb

Thanks.

for the blues scale, you might want to add the b5. Or else, it's just a pentatonic really.

This is my simple system (using C as example):

For C Minor I'll use C, Eb, F, Gb, G, Bb, C.

For C Major I'll either use the above, or the corresponding blues scale for A Minor (that is, A, C, D, Eb, E, G, A).
