So in Lesson 14, Tomo shows a 4 note chord that starts in the F of the high E string as the root, and shows the intervales of the other 3 notes. My question is, is there any type of scale or somehing that goes upward? Or I'll have to always look which notes are in the scale and look for them individually?
Also: Liked the titled "Wait, what?" Because that's how it feels learning from Tomo xD.
I would recommend looking into tomos lessons on triads, where he teaches the basic major triads and its inversions. the thing Tomo does in lesson 14 is adding an additional note to the basic triad: a flat7 (b7) to form a four note voicing. an inversion is based on the same intervals as a major chord but played in different order on the fret board. because of the different order the voicings can span over 2 octaves which gives these inversions different colours and feels in relation to the ordinary major triad. the example you mentioned would be a triad inversion with the root on high e the 5th on the B string and the 3rd on the G string. when you add a flat 7 on the D string you get a four note voicing of a major triad with a flatted 7th. you can do this with every major triad and its inversions.
on guitar this is sometimes confusing because there is vertical and horizontal movement which makes fingerings sometimes complicated. but like Tomo always talks of the triads as the building blocks of western harmony you should try to understand them deeply before you move to more complex chords. I recommend to take your time with the triads and all will fall into place at some point.
