I dislike chords on bass and cause of that i was usually ommiting learning them, but I started learning Fear of the dark by iron maiden and I feel like it's the good time to try to develop the proper chords playing technique. I have a dillema with right hand finger playing 2 and 3 note chords. Right now I'm using (kind of) Geddy Lee style where i pluck my index and middle finger in upward motion attacking 2 strings with each finger - I like that cause it maintain the natural playing position of my right hand, but it feels weird when playing 3 notes chords (I'm creating 2 separate sounds with each finger plucking 2 strings at the same time). On Yt videos I see that a lot of people are using pick style of chord playing (index + thumb attack on downward motion) and I know it's mostly a matter of style, but I would like to know, what is the "standard" proper technique of playing chords ? I will greatly appreciate any help.
