If I was playing chord progressions 1, 4, 5 -- C,F,G Chords Could I improvise any of 1 of those keys in pentatonic at any time,, And other question-- Can scale keys that go together be found the same way as what chords go together? And could I solo the C major scale Then mix it with the F major scale and G major scale? Or just go from the C major scale and just that one scale in those keys?
