do you just pick the most dominent chord

yeah except you don't wannna call it 'dominant' (although i knew what u meant)

the most 'prevalent' chord that 'acts as the root' of a group of chords is the tonic and that tonic/root note tells the root of which scale to play...but that alone is not enough info unless you were just jamming over a root note by itself then you could play any scale at all...but you need to figure out what 'other' notes can be played besides just the root note and to find that out you look at the notes of the other chords

okay,if the tonic chord was all by itself then you could just play any scale that contained the root and 5th

but if other chords are there then you need to figure out what scale the 'notes present therein' are suggesting or perhaps you will have a choice of more than one scale based on that depending on how much of a scale gets filled in (defined) or spelled out by the notes of the chords

say you have something like the following

A5 14 times followed by G5 2 times and this whole things repeats over and over again.Okay obviously A is the tonic and from there you have to analyse what the G5 chord means in that A 'root' context. So you have G5(G D).G and D are the b7th and 4th of A respectively.So now you have to pick an A scale that contains
A _ _ D E _ G so any scale with those notes will work!
R _ _ 4 5 _ b7

Here's the beauty.You can have a min or maj 2nd,a min or maj 3rd,and a min or maj 6th or you can use them all.So if you used them all then you'd have a scale like this:R,b2,2,b3,3,4,5,b6,6,b7 so that's a whopping 10 out of 12 possible notes.But it gets even better because theoretically you can include the #4th/b5th interval for a grand total of 11 notes.But wait there's more.The maj 7 interval can be used as a passing note so as long as you keep that in mind and know where the maj 7th intervals are and that you can use them in passing but not lean on them then you have every note at your disposal.So your scale for improvising over my made up power chord progression is the A Chromatic scale! - and the maj 7th interval is the only one you have to 'kind of' worry about - but as long as it's used as a chromatic passing note,no problem.

12 notes!

That's alot of chromatic fun for improvising with 'and' improvising in such a setting could yield some cool riffs which you could then go back and base a song around and redo the chords afterwards to match your riff or riffs which could give you a whole new take on things and so on.

so many possibilities...

very well explained

when your improvising dont over think, just go with the flow...

Very true.You can sketch things out before hand to get a basic idea of what you can get away with but then when you play just let things flow and kind of lead you and things will begin to take shape.Record your progress.Everytime you think,'aha i've got something here' then write it down or put it on tape or something.You might just get little tiny ideas or you might get a whole bunch all at once.Don't worry about what's happening just let things flow.Feel your way.Hear your way.You can go back later and 'think'.Then you can pick it apart as to what's going on and explain it with theory.
