I come from the surprisingly similar world of brass and have crossed over to playing guitar. That being said, i was wondering how much value tuning individual notes in a chord has to the fretted world? Example. In a major chord, lets use a C maj triad just cause. C E G basic triad. i was always taught that to sound perfectly in tune the maj 3rd of that chord was to be lowered while the P 5th required raising. I dig that one cant make these kind of changes on fast changes, but on slower tunes is something to seriously consider, and in all pro brass settings is mandatory unless you like delivering pizzas over playing. So my question is do you use this technique, and in what settings?
