Is you are really interested in theory - not just short-cuts to learning pop songs, then hit your local school music store and pick up an intro to theory book. Do yourself a huge favor and study theory at a piano instead of a bass or guitar simply because the piano lays out the concept of steps in a literal linear fashion thus making the concept of 3rd, 5ths, etc... much more clear.
Learning theory is about learning music - not an instrument - so it doesn't matter what instrument you use to learn theory OTHER than the fact that piano makes it clearer than any other instrument.
As you learn the basics of theory - how scales are constructed and the various mini-constructs that are derived from these scales, you can begin to see how these things function to make music and apply your new understanding of MUSIC to your bass.
The thread started off asking about ways to understand the 'boxes' and 'patterns' of another musician in an effort to demystify what he was playing. This is not "theory" - this is short-cutting learning songs. Nothing wrong with that - it all works - but since the discussion has spun into theory and people are starting to pop more 'short-cuts' I think it's very important to keep these things in perspective. The things posted here so far, while connected to theory, are still only short-cuts.
Define your goal, SurferJoe46 - and remember, there's no right or wrong goal - no judgment - if you want to learn what Geddy's doing and you're looking for ways to understand the boxes and patterns he's using - that perfectly fine. Just don't confuse the short-cuts being offered as a good way to approach learning music theory. There really is no short-cut for that. You need to start with the basics, learn them and follow their evolution through the more complex aspects (like modes, et al.).
Learning theory in a way that is useful to you as a musician is a long path - a very worthwhile path, but a long one that has no short-cuts. Again - there's nothing wrong with using short-cuts to demystify a Rush song - but don't confuse the little theory-related things with a way to learn theory.
My day has already started and this is just a short note, but I am very interested in all I have read and of course, debunking the ideas I had from years of misinformation in the past.
"Theory" is a loaded word though, isn't it?
Let's suppose that I don't want to write music now or in the future - am I missing something then?
"Improvisation" is more interesting, and I think that comes with Jazz and Motown too, as they are both utilizing some really complex chord voicing and technique.
"Boxes" too are interesting if I could actually learn to invert them - which I think is going to the arpeggio-zone.
Perhaps I also need to tell all of my immediate desires, and also leave the door open for a Phd in Musicology later - if I last that long!
I also know that better enjoyment of the music I play (covers and somewhat limited exercises in Improvisation doing that) are my primary interest at the mo. There are technical walls all around me when I play what I do, but enjoyment to me is really doing a note-by-note redo of an existing song.
Playing above the 9th fret works for me and I recognize the notes on the frets pretty good - I can find all four Cs in the first 12 frets, so I think I am on the right road there anyway.
Actually I can do better than that - but a written test would make it hard to prove scholastically - 'feeling' the notes and just knowing where they are is a lot of fun too. That's where the 'ear' part comes in.
I also think knowing the places where I can pick up another G# that's out of the first five positions is ear candy for me and quite an accomplishment.
When I can nail an eleven fret resolve with no 'oops' notes and do it accurately, then I am at least somewhat as talented as the guy who recorded it the first time.
That's a major digression though. Sorry.
I actually want to know IT ALL - but I see that that's prolly out of my arena right now. I guess we all die with unrealized expectations though so there's no use in going all Maudlin here.
I've got a decent stage presence and rapport with the audience and I feel secure being on stage since I'm a big ham anyway. I just want that extra security blanket and conversational abilities when I am asked why I play what I did and who taught me my fingering style. I've delivered speeches before 10,000+ people a few times, so there's really no stage fright, just concerns about accuracy.
So - where I am now is laying down a good bassline and foundation for the others to use and build upon and basically lending a lot of fill for where the guitars are thin by 'octaving' a few of what I feel are weak spots in the music - it fills the hollow spots with more
subliminal vibrations and just sounds fatter.
If you know "
Something" by The Beatles, you know there are hollows in it and I feel justified in adding a few octaved bass notes to make it more full.
This is the type of freedom I want to achieve by knowing more of the theory I feel.
Now I will go to GC with another friend in a couple of minutes and I'll look there for a fundamental book - er, Primer - if you will - and try to make everyone think I'm buying it for a grandchild.
I shouldda been there many years ago -
