Just wanted to recommend the Fret Science youtube channel, for useful insights on fretboard visualization. The video in the post link was especially illuminating for me when it comes to visualizing the modes more “atomically”. I have no affiliation to this channel, but figured that the somewhat analytical approach of the method would appeal to people here :)
The thing that finally clicked with me when I was learning modes and how to utilise them, is the need for some harmony to bring out the modal flavours. The explanation that modes are just a major scale with an alternate root note never led me anywhere until I started using appropriate chords.
