A lot of pickers struggle with the timing of this tune when trying to play a more advanced Scruggs style version, or when trying to play it like Ralph played it. Those are tough for a few reasons. There's something called anticipated attack that is a tricky rhythmic thing, precise timing of slides required, alternate string hammer-ons, etc., etc. The list goes on
This version is much easier There's no slurs or slides, it uses repeated roll patterns, and there's no anticipated attacks or other super tricky rhythms - besides the unavoidable 5 measure bar we need to play because that's how the tune was written. This is done with a purpose. So you can get to playing sooner. Less initial challenge will allow you to start focusing on things that are more important - like steady timing! After you can nail that down, try a few licks. They show you how we can add in just a few things to get a whole new sound!
