The Cohort: Accountability, Community, Assignments!

“An Amazing Experience!”

Alixe L., student and cohort coach

Who is it for?

For anyone who has taken or wants to take our self-guided, 20 Unit Course, Music Theory for the Bass Player, but would like help with: 

What is it?

It’s Ari’s “Music Theory for the Bass Player” Course with added layers of Accountability, Homework, Coaches and Support, and now new, help from Ari!

What is NEW in this Cohort round?

“It was amazing, really amazing. Just a phenomenal experience and I’m so glad I did it! (Ari's Theory Cohort) really helped me get a handle on my fretboard.” (Alixe L.)

How does it work?

If you have taken the course or cohort before and have dropped off, you can re-start at any of the following Units:

We start with the Cohort Kick Off Meeting

Then, each week – according to a schedule – you have a task to do! It involves watching videos, making a commitment to a specific homework and then practicing that homework for another week. Then it’s time to submit a video of your best shot performing the homework!
You do this in your own time but there is a deadline each week!

You get a dedicated coach who will make sure you submit your homework and holds you accountable!


“I didn’t know what to expect, but I did know that my discipline needed a bump up. There are lots of holes in your knowledge and this fills in the holes and you learn things that you’re gonna use the rest of your musical career. It’s a great foundation. You’re really making music. It’s not just a bunch of dry theory. The other thing that I really loved is learning all sorts of new styles.”

What is the time commitment?

45 minutes 5 times a week to practice and prep on your own. 

When is this?

Our Summer 2025 Cohort will be announced shortly!


What do past Cohort Participants have to say?

“It’s an amazing experience. (It) was good for me because it was structured well. You start building friendships with other participants and you will be a way better bass player by the end. The stuff that’s in the program is so layered, so rich. I was impressed about the amazing amount of support that we had available from the coaches, and even Ari!”

“I was in the most recent Cohort, which ran from June 2021 to March 2022. I wanted to jump in and encourage anyone who might be on the fence not to miss this chance to sign up. It’s a powerful experience that’s very different from taking lessons one-on-one or even from being in one of Ari’s ten-week concentrations. The system of taking two weeks for each unit—one to absorb the material and commit to a submission of some sort, and one to practice, record the submission and post it to your fellow learners—is just the right mix (I found) of carrots and sticks.
I also think Ari is selling the Cohort short by describing it as a “theory course.” Theory is the organizing principle, but if you want you can devote your efforts to technique and dexterity, to fingerboard knowledge, to the skill of applying the theory in real time (which is a whole different thing than knowing the theory), or wherever you feel you want to improve. And the supportive and encouraging atmosphere makes it much more likely that you’ll do what will really help you the most: find the weakest points in your skill set and work on them, rather than just playing what you already know and repeating what you already know how to do. (Does that sound familiar?)  
I could go on but I won’t. You should grab this opportunity as long as you have the motivation and the (not unreasonable) time to devote to it. I hope to see you there.”

If I have already done it, does it make sense to do it again?

Asked why he has done the course 6 times so far, Coach Peter says:

"I guess the biggest reason was that I saw the value in systematic, focused practice. Not just learning songs and learning through songs but also learning and studying principles and ideas. I never studied music in my youth, so I did not have experience studying it. But, I knew from other learning in my life that this kind of focus and organization is necessary to excel."

Who are the coaches? Are they Bass Teachers?

Coaches are students like you. They are not bass teachers (well, some actually are!) but with us their main job is to hold you accountable and support you as needed along the way.

In order to become a coach with us they had to: 

Is Ari involved, too?

Yes! In these new rounds she is! There are meetings you can attend live on zoom where Ari reviews your submissions and puts on a mighty theory practice session. Bring your questions, bring your bass! Watch the rerun if you can’t make it!

When is the next one?

You can take the non-guided version of the course at any time, but you can only join the Cohort when we start a new one. The only one currently planned starts on February 4th, 2024.

“I joined the cohort in January and have found recording myself to be invaluable. It lets you spot areas of technique that you should be concentrating on. The Cohort is excellent and I can honestly say I have played for a minimum of 30 minutes each day since… it started. Everyone is so friendly and supportive. I feel like I have improved more in 4 weeks than I did in the last 4 months.”

“Recording myself has enabled me to see the progress I’ve made by the practicing I’ve done. It serves as a record of my progress as I look back over time at the recording to assure me of how far I’ve come in my bass studies.”

Recording Yourself

Is an important centerpiece of the cohort.
The payoff is well worth the effort. Listen to what our recent cohort participants have said:
