[quote name='62P-Bass' post='497192' date='May 25 2009, 10:57 AM']I find it more useful to think about the number of the note in relation to the chord/key, rather than the actual note name. As time goes on you get better at understanding what effect each interval has against the chord, which will be the same regardless of key. This should help you to improvise as you will start to know in advance what each note is going to sound like in that context. Also, because of the layout of the bass fretboard and string tuning, the fingerings will always be the same which is a big advantage.

I agree with this. Knowing the scale degrees is invaluable because you begin to see what chords are likely to occur within a particular key, and if you know which of those degrees is major and which minor (for example), you can quickly find the root of your chord and figure out the pattern you want to follow. It's all related (this is not news, I know ), and it is a LOT easier to figure out and use if you learn the notes, which in turn is made a lot easier because, as Andrew said, you are doing things [i]in context[/i], not just looking at notes scattered over a board. For me, learning the notes, practicing scales, and finding the triads has opened up my playing immeasurably. It's just a matter of doing it every day, a bit at a time. I guess if I felt I could play better going strictly by ear, I wouldn't bother with doing things more systematically; but for me, this is what works.
