Hi there, Chief.
I don't know your past musical training and experience, so I'll assume zero.
All the posts about getting instruction regarding proper technique are right on point. The most common mistake I see, however, which IMO most frequently causes new players to become frustrated and quit or significantly retards their ultimate progress (especially would-be guitarists), is to approach their instrument as solely or primarily a study in technique and short changing the importance of learning music theory (including sight reading).
If you've already had a few years of piano training, this is easier to recognize. The music theory you learn playing the piano doesn't have to be re-learned for subsequent instruments, which then
can be approached as primarily stduies in instrument technique.
When I was 7 years old and my hand wasn't quite large enough to fit around the necks of the guitars available to me, my mother decided to give me accordion lessons instead and, of course, she saw that I practiced every day. By the time I was in the 7th grade, the junior high band/orchestra instructor had me playing a different instrument every year. What a treat! He and I would sit down a couple of weeks before school was out and I'd get to decide what instrument I wanted to play the next year. He'd give me a 2-week crash course in technique after school, loan me a school instrument and instruction materials for the summer and I'd report--ready to march with the instrument--in the fall. I played tenor sax, baritone sax, various types of drums and had a ball.
When I decided to try guitar again (at age 14 and, soon thereafter, electric bass), it came very quickly because I could focus almost entirely on technique. I knew scales and arpeggios and chord inversions. I could read trable and bass clefs. I understood key signatures and time signatures. I knew the circles of fifths and fourths. And I still use this information every time I play. (Thanks, Mom.)
Good luck with your bass. I hope you enjoy playing it as much as I have and for as long. Just take the time to learn
music, in addition to learning the bass, and it will happen.
