Firstly, I have no idea where you’re at in your bass journey so forgive me if this is redundant.
My 2¢:
Learning music (ultimately an instrument) is analogous to learning a language. When someone is new to a language or wanting to advance their skills, what’s the first thing they should do? Learn a bunch of nouns, verbs, adjectives, syntax, sentence structure void of conversational context right? Nope! The best thing is to learn is appropriate ways to respond to common day-to-day conversation. Once they are comfortable with that, then they can dig out the thesaurus and see what other words can be used to go beyond the basics. What’s even better if they’re conversing regularly with people that are fluent in the language as they’ll be able to pick up the context of advanced words and build vocabulary much faster. When learning anything, experience come first. Labeling comes second.
I got the impression that the OP had already worked through a Frank Gamble book.
It’s pedagogical nonsense to teach beginner to intermediate players scales and triads and any form of theory void of a musical experience they can contextualize it with. When the language learner can hold down a moderate conversation
then you can say, “by the way, ‘dog’ is a noun, ‘run’ is a verb, ‘quickly’ is an adjective, etc” but by no means should the labeling be prioritized over the learning experience. When you think about it, children are fluent in their home language before entering school. They have hundreds to thousands of words to contextualize their learning.
Translated into a musical context: learn a bunch of songs, cliche bass licks, and other foundational “roles” of the bass in different genres. I’m not saying it’s not useful to know your major/minor pentatonic and major/minor diatonic scales. Warm up with them, play them to a metronome, but that’s about it. A warm up. In my opinion, there’s no reason to be shedding “the 47 ways to use 5th mode of Spanish Phrygian”... unless you’re an advanced player, or just find it fun. I’m not against learning things for fun. But as a pragmatist, I tend to lean away from scales other than for warmups. Find some pieces to study that are fun and challenging. I learned
way more from learning Sir Duke then any scale method book... and that was after a degree in jazz studies
I realize this was a bit of a rant and more than 2¢!
