Ideally your soloing needs to reflect the underlying harmony.
I'm assuming your basic 12-bar shuffle, the harmony of which is:
I7 - I7 - I7 - I7
IV7 - IV7 - I7 - I7
V7 - IV7 - I7 - V7
which in the key of A would be:
A7 - A7 - A7 - A7
D7 - D7 - A7 - A7
E7 - D7 - A7 - E7
Whatever you play at any given point in time needs to reflect the chord that ...
In Blues in A, the IV chord is D. Over that, as you state, , maj. pent., min. pent., maj. blues, min. blues are the main notes most use (ignoring modes for now!).
Let's consider all the notes those entail. D, E, F, F♯, G, A♭, A, B, C. In fact, it's probably more simple to quote 'avoid' notes! They're B♭, D♭ and E♭.
A lot of those ...
Chromatic and blues scale are two very different scales.
In Western music, there are only 12 notes:
C C# D D# E F F# G G# A A# B C again
If you play all these notes together, the scale is called the chromatic scale (probably named because it contains all the "colors"). Obviously the chromatic scale in all keys are exactly the same.
The blues scale can ...
Your method of removing the tritone doesn't match up with Google results for these scales: R 2 3 #4 6 and R b3 4 b5 b7 where the point seems to be include the tritone above the root (should be called tonic, roots belong to chords.)
The sources listing these scales are - if not entirely - mostly guitar sites. Personally, I'm skeptical when reading them. ...
It's not necessary for all the chords in a sequence to be diatonic, and here they're certainly not. There were several soul type numbers in the '60s that used all these chords in the same song - same verse, same intro riff, even!
The best bet would be E. I'll try to explain. In blues type music, there's some borrowing from parallel keys, and here, the G and ...
THIS IS HOW TO USE IT.
It can used to play "outside" and best works with Fusion jazz, or possible some weirder metal styles. If you are not into those styles or modern discordant classical it probably won't be useful.
It will work best over a grove if you want it to blend
So you play a solo in the main key and in the middle of it you start playing that ...
...NB, it's the notes in the scale I want to memorize, not the keys on the piano keyboard. If I've memorized that C-minor is the naturals except for A flat, B-flat and E-flat I'll have no trouble finding those notes on the keyboard.
When worded that way it sounds to me like you really want to know the keys signatures not really the scales. The two are sort ...
