If you really want to learn the theoretical basis for chords and scales: Christopher Schlegel's tutorials are the way to go.

Rock and Blues.
I learned that melody loves chord tones so your strong notes should be chord tones from the same background chord being played.
In my example the band is playing a G C D progression and I am playing lead guitar.
If your melody ONLY use the G minor pentatonic you have the 1 3b 5 for the G "chord tones" in the scales making this actually G minor. The C chord tones you have the 1 and 5 to play with. The D cord tones you only have the 1. This seem a little limiting as the chord tones should be your stong notes and the remaining scale notes should be more passing or connecting notes to other chord tones.

note: below when I say 1 3 5 I mean the 1 3 5 to make up the chord not the scale numbers.

This is why I'm asking if you switch scales as the background chords change.

Does this make sense?

Thanks
