I've been playing bass for about a year, so pardon my question, what is the relation between chords, arpeggios and scales? I always learnt and played scales, but in order to learn this new jazz bassline my teacher has me do, it only shows the chord (G7, C7, etc, etc) and no notes. How am I suppose to play it? Im trying to learn more arpeggios but I can't seem to put two and two together and see what arpeggios have to do with chords. I also am wondering what the chord tone (if that is the right word) means in the difference of playing it, like the different of a diminshed chord and any other chord.

I hope I'm not getting ahead of myself, is there anyway I can learn to play chords?
