Does the five blues boxes cover playing in any Key? If so how do you berak it down?
Basically, yes they can cover all keys but...Be you must be aware of the "Root note" or key for the scale. If you shift the root note as the starting position, you are also shifting the key of the scale.
The boxes are shapes and the shapes can be moved to different positions... so for instance if you were playing the E minor pentatonic scale and you shifted the "Root" from E to F but played the same pattern playing from the F as the root note... that would be the F minor pentatonic scale...
The order goes like this
E F F# G G# A A# B C C# D D# and back to E
Let's say you were playing box 1 from the 5th fret. That would be the Root or Key of A [6th string 5th fret is the Root note A] in this case.
If you play the same box 1 pattern, from the 3rd fret that would be the Root or key of G [6th string 3rd fret is G]
I hope this helps. It can seem confusing at first but give it a little time and it will become more clear.
Questions...?
Yeah, you simply move/shift all the boxes the same distance. For example, if using A blues boxes but you want to learn them in C, you shift them all up 3 frets higher, from A to C. From A to D would be 5 frets, to E would be 7 frets. And so on. Does that make sense?
