Easy to smile for Craig who just finished a round of technique drills…

Imagine it all starting to make sense...

This could be you:
You go to a jam and the drummer kicks things off with a catchy beat. Then the guitar player drops in a few chords and that’s when you jump in with your own grooves and fills – totally on the fly and it feels amazing!

Expressing your ideas in a manner that garners the respect of your bandmates, friends and fans alike and it feels amazing to be able to do that! 

That’s because when you start learning a strong foundation of theory and technique, everything begins to fall into place:

Here's What People are Saying...

Our students are raving about Ari

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. And I am obsessed with helping others realize their musical potential.

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.

Myth Buster

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 competenceconfidence, and ability!

This beginner-friendly “Core Principles” Course shows you the guiding principles that lead to a strong foundation in theory and technique so you can create your own grooves!

Your bass and an internet connection. 

No need to be able to read scores. Learn theory as shapes first, it makes learning to read much easier later. We have included TAB and score so you can figure out the examples with the guidance in the videos. 

Yes you will, in a variety of styles!

This is a beginner-friendly course! Intermediate level players will also get a lot out of it!

Yes start right away! You have lifetime access!

We also offer a data CD for the computer. You need a CD player to play it (which is rare these days). If you are interested you can purchase it here.  

No. While the subject matter is in some ways similar – theory, technique, groove creation, this is a shorter course. All new videos and completely new drills, so there is zero overlap.  
If you are curious about Ari’s teaching but not quite ready for the “big course” yet, this is a great starting point!
If you have already done the 20 unit course, you will find this a collection of fun drills that will reinforce what you have already learned. It will be useful and not too challenging!
