So here's my deal, I know a few minor and dim arpeggios on 4 and 5 string bass and I have a general idea of how they work but I want to expand on that with a 6 string but unfortunately I am having trouble because i don't know where to go or how to connect it to scales and other arpeggios. I'm trying to engulf myself with more music theory because I have always been one to feel the groove and play on how it feels but never taught myself things other than those arpeggios, some tapping, time signature changes and tempo modulation. If I could get some input on what scales and arpeggios and how to use them to my fullest to better my technical death metal music that'd be awesome. All forms/genres of music would help me especially jazz and classical.
You already know how to create an arpeggio ... it is the same thing over 6 strings, it is just that you can cover almost 3 octaves in one position.
Arpeggio are just stacked 3rd in a major, minor, dim or aug fashion. Nothing else, nothing more. No need of a book for that, just basic theory knowledge.
