yeah man, that stuff can get really hard to coordinate. You have to start off easy. And if you already got tapping down i suggest learning the first (bass) part down REALLY good, and basically be able to play it with no problems, even wihle talking to someone or singing, (is this what muscle memory is? lol)
once you got the first part down 100% you add in the "solo" part
i should work on that too
