“Just play what you feel” is bad advice.
It's applied THEORY that will make you a better player.
"Theory is so complicated!"
Right? WRONG!

Hi I’m Ari. Bassist, author, educator. Groove enthusiast and learning nerd.
As a bassist, I have toured/played/recorded with a variety of rock, Jazz, and funk bands, I have worked with some incredible producers (Keith Olsen) and musicians (Paul Hanson, Muriel Anderson) and I toured Brazil with Stu Hamm as a duo.
As a bass teacher, I have taught at London Bass Day, Gerald Veasley’s Bass Boot Camp, SBL, Truefire, notreble… I even ran my own music school for a few years before gigs took me back on the road.
One thing to know about me is that I teach because I am absolutely fascinated with the learning process.
When I started playing bass, I excelled very quickly because I had an amazing teacher who taught me using a powerful method. This method transformed my playing so quickly that I passed a bunch of high-level university auditions and even tested out of entire classes at university even though I had been playing for only a very short time.
That’s what, many years later turned into one of my books, co-written with Wolf Wein, called “The Pattern System for the Bass Player”. I created entire systems of learning based on some of these ideas and wrote books and created courses together with Wolf. Our bass books have sold over 30,000 copies and garnered rave reviews.
I started teaching online in 2009 and have embraced technology as a powerful learning tool since then, never losing sight of the importance of providing feedback and personalized guidance to learners.
I also utilize the power of learning in groups: our first cohort with volunteer coaches ran in 2018, and Masterclasses started in 2020. Our Live Practice Membership has been running since 2022.

We lead you step by step to creating your own grooves and fills with the theory concepts.
This course uncovers how music is put together. Understand the underlying logic and all begins to make intuitive sense!
Ditch the TAB and use your new knowledge instead. Create your own variations, fills, solos and improvisations.
Stop chasing what you hear inside but rather use your new knowledge to hear it before you play it!
Once the course is paid in full, you have lifetime access.
Yes, we offer an unconditional 30-day money back guarantee. If you are not satisfied for any reason, do not hesitate to email for a full refund for the course.
Buy completely risk-free and get lifetime access to the material once the tuition is paid in full.
The cohort Add-on portion of the course is not refundable because we have limited seats available and organize coaches who work with you.
No need to be able to read! It doesn’t hurt but if not, we got TAB and descriptions for everything!
Learn theory first (shapes! shapes! shapes!)
My course combines that with good technique. After this course, we do the Pattern System, Reading and Rhythm, and then some advanced theory, and you are truly unstoppable! After this course, reading becomes a breeze! Boom! What a shortcut!
Do it this way around, not the other way. Utilize your strengths rather than fight against your weaknesses.
That is 100% A-OK. You will work with the book as you make your way through the course. The book is a handy reference/encyclopedia. We put the material to use as we go!
Yes! You will be creating and playing your own Basslines, licks, grooves & fills, and even solos! Usually along with a jam track, and trading off with me! This is really at the core of this course. And mighty fun, too!
Yes!! This course contains lots more information, exercises, and concepts than the book. It refers heavily to it, but it goes way beyond it.
Lots of additional material, videos, and applications that can best be shown in videos. And, the core of it: the step by step approach, with each unit building upon the next, using the material in the book in more and more challenging contexts and applications.
The 89 videos that come with the book demonstrate the shapes shown in the book. They are demonstrations so you hear what the samples and shapes shown in the book sound like and how playing them on the fretboard looks like.
The 21 hours of video in the course are course videos. Ari shows you concepts on how to use this material, demonstrates drills and exercises to play along with and plays “call and response” with you. They are instructional videos.
The course references a few pages of the book and the corresponding book video demonstrations of these book pages in the intro section of each unit. So whether you have already read the book or not
Yes, if you are motivated and enthusiastic. If you are just starting out you will need to pace yourself and go at a slower pace.
A good rule of thumb is to allocate at least two weeks for each unit. I have included a beginner crash course as well and instructions as to how to proceed through the course if you are a novice.
Yes! Intermediate to advanced players who are looking to improve their theory and technique will find a treasure trove of useful exercises here.
Yes, you can start the course at any time and complete it at your own pace and on your own terms. You have lifetime access.
We offer a no-questions-asked 30 days money-back guarantee on the course. Your commitment is risk free.
Try it on for size and if you’re not completely convinced that this course is powerful for you, I will promptly refund your money.
What about the Support Option
AKA “BASS THEORY COHORT”?
“Cohort” ˈkō-ˌhȯrt
a group or team who works together on a worthwhile goal.
“Bass Theory Cohort” ‘basˈthē-ə-rēˈkō-ˌhȯrt
a group of awesome bass students doing the 20-Unit Theory Course together with the help of success coaches & each other!
Alixe L., student and cohort coach
Doing a big online course on your own can get a little lonely, sometimes overwhelming. If you’d like some help, motivation, accountability and company, we got you! Twice a year we run what we call the “Theory Cohort”.
As a participant of our Course Cohort you do ten units of the course with your personally assigned success coach (who will help hold you accountable) and a group of peers, who will cheer you on and support you. You submit homework assignments and can ask Ari questions in meetings. It’s a lot of fun and will help you create a great practice habit for life!
Meet some of our 2024 New Year’s Cohort attendees. Hear them play below!
is a group of students who start and complete a course together. They move through the course at the same pace, doing assignments and submitting them by a weekly deadline. This setup allows them to support each other, discuss what they’re learning, and often work together on projects. Think of it as a class where everyone learns and progresses together, even though it’s online and everyone practices on their own.
Reserve 45 minutes 5 times a week and 30 minutes every other week to shoot and upload your video(s).
No problem! You can work ahead and you can catch up! And if you have a smart phone and a travel bass you can even record yourself on the road.
Yes, if you are motivated and enthusiastic, go for it! Your coaches and peers will help you and cheer you on! Super supportive vibes will help you thrive!
Yes! Inspire your fellow cohorts and show off your stuff! The course assignments are designed such that if you have a lot of facility you will be able to use it!
Our Cohorts start twice a year, around New Year’s and in summer.
We run the cohort twice a year, around New Year’s and in Summer. You can always start the course on your own and join up with a cohort later (many do this!)
The cohort Add-on portion of the course is not refundable because we have limited seats available and organize coaches who work with you. It’s also an investment into yourself, a commitment you make.
We offer an unconditional 20-day money back guarantee for the course materials. If you are not satisfied for any reason with the course, do not hesitate to email for a full refund for the course.
Buy the course completely risk-free and get lifetime access to the material once the tuition is paid in full.
Go for it! We sell only the cohort add-on for this purpose. Note that since seats are very limited and you get an assigned coach, there are no refunds for the cohort add-on only.
Our cohort coaches are not professional bass teachers. Instead, they are successful course completers and former cohort participants whom we carefully select to be cohort success coaches. Each coach is assigned to 3 to 6 students.
Their primary role is to hold you accountable, assist you if you encounter any obstacles, and provide ongoing encouragement.
According to our surveys, 80% of respondents reported that having a coach check in with them made a significant difference in staying on track.

Learning hundreds of songs with TAB will not make you a better player somehow/maybe/hopefully!
In reality, all it does is turn you into a walking, breathing karaoke bassist – only able to play the songs verbatim, and only in the key the TAB was in. Originality, agency, or real musical skills will rarely emerge on their own like that.
The way to get better is to get competent. To understand how music is put together. And it does not need to be hard or boring.
Do my fun theory drills that use improvisation and get the competence by creating theory with grooves to help you understand how you can make it all work.
The way to get your fingers to cooperate is to learn to play with relaxation and feel, just like we practice it in my Finger Kung Fu sections in this course!
Find your creative self in the many groove and fill drills in this course that not only put skill at your fingertips, but a confident smile on your face.
Real confidence requires real proof – and it comes from finally knowing what you are doing.
Done the Ari Way, theory deepens the magic giving you more options, new insights, better ears and an enormous amount of understanding!
Theory creates true competence, confidence, and ability!
No matter where you are in your bass journey – my 20-Unit course teaches you all you need to know about music theory as a bass player and how to use the knowledge so you can start to sound musical right away!
