Ari's Rhythm Matrix
Groove is what hooked us in the first place. Now it’s time to own it.
Feel the Beat. Fix Your Timing. Grow Your Groove.
Many musicians assume their rhythm is solid – until they (or worse, their bandmates!) realize something’s just a little off.
The difference between good and great groove is subtle but game-changing. It’s not about how many notes you play or how much theory you know – it’s about how it feels.
- If your fills don’t quite land…
- If you get lost or feel like something’s off but can’t explain why…
- If syncopation throws you off
- or you've been told to “play less” even when your lines seem solid
then rhythm is the missing piece.
Often the focus is on what to play, but not how to make it groove.
That’s where Ari’s Rhythm Matrix comes in.
You’ll build your internal clock, sharpen your rhythmic intuition, and reach new levels of precision so you can stop second-guessing your timing and start playing with clarity, creativity, and intention.
If you want to truly lock in, rhythm has to live in your body – not just your head.
Rhythmic creativity and counting use different parts of the brain.
Counting relies on the analytical side, which can disrupt the creative flow tied to the intuitive and imaginative side of the mind.
Ari’s method bridges this gap by systematically training your rhythmic instincts, that results in rhythm that feels natural and fluid, and becomes expressive.
Why Groove Practice Matters
It’s not the number of notes that makes a great groove.
No amount of theory or flashy scales can make something feel good.
The “groove,” the “pocket,” the “feel” – these elusive concepts drive the music and forge a deep connection between players and listeners.
Yet rhythm, the foundation of it all, is often misunderstood or dismissed as simply an innate talent.
The truth? Rhythm is a skill that can (and must) be practiced, refined, and mastered because it changes everything:
When it’s solid, your playing feels grounded, musical, and alive.
That's where Ari's Rhythm Matrix comes in.
What is the Rhythm Matrix?
It is a step-by-step method that teaches 16 simple rhythmic patterns, which unlock the entire world of binary rhythms. Ari teaches those using a simple trick that helps you get them into your body with ease.

Here's What Ari's Students are Saying...
I just finished Ari’s Rhythm Course and I can’t stop thinking about how awesome it was.
She has come up with such a great way to get the rhythms into your body.
Ari teaches us to feel the subdivisions in our bodies using words. It’s so simple but so deep at the same time. I loved the songs she used to teach us examples from the rhythm matrix and the idea that you can isolate the rhythms from those songs and use them when you are practicing other material.
Thanks so much Ariane Cap for your brilliant, creative teaching!!!

First of all I wanted to tell you how much I've learned in our class and it has really help me understand the rhythms. Your teaching methods are amazing.
I now find myself trying to identify the rhythm patterns on tunes as I drive to work and transcribing some of the bass lines that constantly bounce around my head.

Over the past six years, I’ve tried many different teachers with their different teaching methods, and time after time, I return to Ari’s courses. I have come to realize that this is the only place I need to be to learn everything I need to continue growing in this journey.
She has the most impressive process of instruction. She obviously loves to teach. All her courses are interconnected.
No matter which piece of the puzzle you focus on, whether it be theory, rhythm, patterns of the fretboard, technique, etc., she manages to include insights into all the other aspects of what she has to offer. It’s a beautiful thing.

I started using the Rhythm Matrix approach to Sight Reading and Transcribing Rhythms from Audio. The counting "1 + 2 +, 1 e a +" drove me crazy when reading and transcribing rhythms.
The Rhythm Matrix makes my job so easy when reading, and figure the rhythm when listening in the car.

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 and with support: check out our Cohorts and Practice Memberships.

FAQs
Who is Ari’s Rhythm Matrix for?
Bass players who want better time, deeper groove and a solid internal clock. Great for beginners who want a clear rhythm foundation and for experienced players who want to clean up timing, feel and consistency.
What will I learn in this course?
Subdivision, feel, syncopation, rests, ghost notes, accents, metronome control and how to place notes with confidence. You will lock with drums better, groove harder and stop rushing or dragging.
How is the material taught?
Through embodied drills and bass application. You will clap, vocalize, tap, count, move and then put it on the bass with lines, grooves and fills. The body learns first, the bass locks it in.
Do I need music theory or reading to start?
No. The course works without prior theory or reading. If you know some, you will use it. If not, you will still improve your timing and groove.
How much practice time do I need each week?
Plan for 20 to 30 focused minutes per day, five days a week. Short and consistent practice wins. I show you exactly how to structure the sessions.
Do I need music theory or reading to start?
How much practice time do I need each week?
Will this help with odd meters and syncopation?
Yes. You will learn how to count, feel and subdivide so odd meters and syncopated lines make sense. The same method improves straight time and swing feel.
Do I need a metronome?
Yes. Many drills use the click creatively, including offbeat and sparse click practice. You will also practice without a click to build your internal pulse.
Does this include live support?
The course is self paced. If you want deadlines, accountability and feedback, you can add a 12 week Cohort that follows selected units and includes live check ins.
How long do I keep access?
You get lifetime access to the course videos and downloads. If you join a Cohort, live meeting recordings are available for the duration of the cohort.
What gear do I need?
Any working bass, a tuner and a metronome or metronome app. Good monitoring helps but no special pedals or interfaces are required.
