30s I appreciate that.
I played saxophone and flute in middle school but didn't get a lot of theory at that stage. I've learned a lot in the few weeks that I've been reading up on bass. Scales aren't just random notes you have to memorize who knew?
I know it's going to take time to learn. Time line is more about since it will take awhile what are realistic goals for the short term. Both for weighing if I have to time and dedication and for what practice would look like.
So I get the math of chord tones but when looking at a chord sheet are you playing just roots, R-R-3-3, R-3-5-3, R-R-5-R, etc and is it player preference or are there guidelines?
As an adult beginner. If you can get lessons, you’ll probably be much better off. That being said, I find weekly lessons too slow, though the instruction is more direct.
Things you’ll in general need to study to play the bass competently:
1. String muting techniques
2. Fret hand position
3. Plucking hand position(s) depending on your style
4. Chord/scale relationship
5. Famous bass lines to turn those scales into bass lines.
Do you want to play covers or originals?
If you want to play covers, then it’s easy. Learn technique of playing the bass instrument. And then learn the songs you want to play. Tabs available online.
If you want to do originals, that’s a bit harder. Learn technique of the bass. Learn songs from artists near your style of music. Experiment and find a band that you can work out music with.
For what it’s worth I think after 1-2 years of practicing almost every day at least 30 minutes I was in my first gigging band as a bass player. I have a music degree in saxophone, so I do have a lot of theory knowledge. I’m 34. I’m in year 4-5 of playing bass, and I now play out a good bit. Been through a bunch of bands and making my way up the ladder of band talent and booking.
But as I said before. Anything you do in life, you’re probably going to do it a lot, and you’re probably not going to make a lot of money doing it. So might as well enjoy it.
