Interesting read. I am 48 and have now been playing in bands solidly for 7 years, starting in a death/thrash band, then a punk band, then a voodoo blues band (when I switched to double bass) and now my folk/country/flamenco outfit (still playing double bass). Throughout all of this I have struggled badly with any thing theoretical. I play patterns and learn bass lines by position on the board. I really have very little understanding of what I am playing. Thankfully I am quite good at learning lines and patterns and reasonably dexterous. However, I would dearly love to actualy understand what it is that I am doing on a bass. Reading BassChat does give me some major feelings of inadequacy as other BC'ers reel off theory, whether basic or complex, and I just don't get it. And I have yet to find a book that makes it any simpler.
