"Technique is the physical execution of producing the notes from your instrument."
 

I believe you only need enough technique to play what you hear. Aside from basic exercises to condition your hands and to build strength and endurance, technique should come more from the practicing of playing music than from just exercises alone. How often do you think about how to use your vocal chords (the instrument for the spoken language) when you talk?

You don't, so I think you need to get the physical approach to the bass like your vocal chords. You don't think about it, it is just there for you to use. Most of the technique portion of my program is in the practice of the styles, reading, and scales part of the course.
