The modes explained clearly

What are the major scale modes? How do they relate to the pentatonic scale? What on earth is "brightness ordering"? All this and more are explained herein!

This is a remastered and expanded version (with new, improved animations) of the first Fret Science video. The part on using the pentatonic scale to quickly access the modes was split out into another video, and this just focuses on explaining where the modes come from and why they sound the way they do.
