Yeah, it gets harder as it goes for sure! Which is case-in-point why I don’t generally teach full songs to beginners, they might sound easy in one spot and then suddenly jump a few months ahead in difficulty. Starting with riffs = 
And yeah @lucas9000, I’ve been using the Cirrus a lot less in lesson videos lately, a lot of people benefit from having the dots on the fretboard to follow. Plus I’ve been developing a bigger crush on Fender basses.
