Tone Matters. Use It Well.
That sounds like an excellent resource. The terminology for what you say he's doing with resolutions would be voice leading.
As far as "safe" places to land on a chord I'll give a very broad and general list of safest to most risky. I'll put the extensions in parenthesis.

This doesn't account for alterations for half steps in either direction specifically (something like a IV would include a sharp 11 to keep with the parent key assuming it has been established as major) but the same sort of general principle applies.
Both Robbie Calvo and Josh Smith have published TrueFire videos that showcase the elements of theory, but do so in a non-scholastic manner...most of the course is ear-training and knowing your fretboard so as to discern what notes will sound "good" when they resolve, or create extra tension, if not resolved. The lessons dive deeper and encourage chord structure knowledge so as to recognize "landing" (resolution) notes of the chords used.
Calvo's Sweet Notes does exactly that but does so in a very melodic and musical way, not so much skewed toward the atonal scales we hear more often in modern music today.
Regards atonal, a teacher once showed me how to use a I-Major scale (Ionian), but to play it one half-step down in VII-half-diminished scale (Locrian). Although I don't recall the reasoning or chordal changes involved, the technique immediately creates a jazz fusion feeling to any I-Major scale. (It would have been good money well spent to continue lessons with this teacher, but he lived 67 miles from my home some years ago, and booking lessons with him was rather difficult, to say the least.)
Rick, have you heard of this type of "half-step down from major scale" style of playing before? If so, could you expand upon it please, so as to provide us students with a wider knowledge base?
