I guess I didn't catch what you were asking then...rbarata wrote:What I mean is this: If I play the CMajor scale straight, without any variations, on top of chord progression Dmin7 Gdom7 Cmaj7, I should start the scale in D when the Dmin7 chord starts and be sure that I reach the note G simultaneously with chord Gdom7, the same to the C and Cmaj7.
If your intention is to simply play linear scales root-to-root over a progression, then you might want to jump or navigate to the roots to start "at the right place". But if you're talking about using linear scale runs as a melodic device, then generally speaking it's not critical (nor is it necessarily desired) to align root tones with chord changes. For example, the 3rd (major or minor) is an important tone relative to a particular chord -- you could start or center a melodic idea around the 3rd and eventualy resolve to the root of the chord (or not at all). Here's a contrived example using linear scale runs but focusing on 3rd tones (I put the note names under the tab, and chords on top):
Code: Select all

I guess the point is your melodic ideas don't have to start/end on roots, but the tones that you choose to play over a particular chord should make some harmonic sense. And the stuff that is not "correct" should at least be getting you to some point of melodic/harmonic resolution. If you play too much "incorrect" stuff it starts to sound like you're just playing in the wrong key. I think the rules here is: if you're playing something you shouldn't be playing, then it generall won't sound good.
The pentatonic scale patterns are probably the single most important thing to master on guitar, IMO. They are used everywhere, and you can do a heckuvalotta cool stuff just with pentatonics. They're also good for recognizing repeating 4-note box shapes over the fretboard in different octaves... I would recommend approaching all 5 pentatonic shapes/positions upfront, rather than get stuck within one or two shapes. The sooner you can think up/down the fretboard, rather than just across the strings, the better. I posted a couple of links on page 2 regarding pentatonics, and in particular this "hopscotch" exercise, which I think is a really good way to practice pentatonic shapes:As I was playing it, I could "ear in my mind" a typical blues chord progression and noticed that the pentatonic scale it self is a blues solo (or is it the other way around?).
