FORMULA
The proven, step-by-step process that shows exactly how to understand music and play anything you want.

You have a dream. A goal. You want to be able to use the piano to express yourself. To play anything you want to play.
Accomplishing this requires a few things: understanding, practice, discipline and a clear path to follow. A plan that tells you exactly what to do and when to do it.
Without it, the process can be overwhelming.
Chord Piano Formula and its 8-week Bootcamp provides this support - showing, guiding, holding you accountable and making sure you actually follow through.
It will fast-track your growth and save you years of frustrating trial and error.
Whether you're just starting out and don't know a "c" from a "b," want to make your playing sound more mature by choosing more interesting voicings & broken-up patterns, or are ready to start adding fancy extensions and licks, Chord Piano Formula will help you:
Contrary to popular belief, you don't need to read sheets to play piano. Think of guitarists. They learn to understand chords - music's building blocks. Piano and guitar are in fact very similar. Chord Piano Formula teaches piano using this "guitarists' approach" - you won't need sheets.
Even though music might already be the coolest thing ever, it still requires discipline to learn. Chord Piano Formula eases that pain, making learning fun by being set up like a game. Grow levels by acquiring eXPerience- & Ability Points completing lessons, exercises and passing quizzes to earn badges, certificates and unlock cool extras.
The Hack the Piano methodology is based on years of experience from within the field. Made by actual musicians who have been doing this for a living for decades. This is how we do music. In Chord Piano Formula we add that level of unprecedented guidance to help you learn the language of music.
There’s a reason this program is so popular. Our strategies work across all styles of music and for musicians at virtually every stage of their journey.
Next to a carefully planned out, comprehensive, step-by-step online course plan, the 8-week BootCamp adds coaching calls, workshops, accountability, feedback, exercises and assignment-grading. It's the closest you'll get to actual private lessons from a professional musician.
We’ve always backed our programs with a 100% satisfaction money-back guarantee. So you can rest assured that your investment is safe with us.
Whatever you wish to play - with scalable lessons, exercises & assignments; select your own music and add-on courses to personalize your journey; plus accountability built right into its 8-week BootCamp- Chord Piano Formula shows you exactly what to do when. It guides you every step of the way so you can focus on what you want to learn in the fastest, most convenient way possible
Every week you'll receive an email with detailed instructions + link to the online course, where you'll find that week's lesson, exercises, assignment and workshops (2 per week).
During the week, you'll practice your newfound skills using the scalable exercises and dive deeper into the main lesson's subjects, applying them in self-picked add-on course modules.
At the end of the week, you turn in your assignment to have it graded, receive feedback and collect your points to unlock custom extras - all using music of your own choosing.
Twelve, 90-minute workshops with demonstrations, exercises and hands-on musical breakdowns - all completely scalable - is where you'll get your hands dirty and mind spinning with all the new musical ideas.
Chord Piano Formula consists out of 6 core modules that each break down one of music’s 6 layers plus 28 add-on courses that allow for a deeper dive into the subjects of your choice. All course materials - including workshops, streaming videos, audios, transcripts, handouts and add-on modules - are within the online student environment.
The Formula's master-course guides you, hands-on, through each of music's six layers: musical structures, chords & voicings, rhythms & patterns, extensions, embellishments, (re-)harmonization.
As this is an intensive training program, you're expected to put in some work yourself. Complete assignments, 10-30 minutes of study time per day and prep reading for the next lesson.
12 full 1 hour+ workshops (16hrs total) go into each of the main piano-hacking layers in a hands-on matter.
In the coaching calls Coen answers any question you might have.
Whether you are more of a beginner to get an intensive overview-introduction, or a more advanced player, reviewing and diving deep into chord-piano practice and theory, this scalable program will boost any player's progress.
Hi! I’m Coen.
I love to play the piano, sing, write, stay fit, eat, be healthy and take unconventional approaches and chances in life while teaching others how to do the same.
At age 17, I taught myself how to play piano. 4 years later I got accepted into the Conservatory of Amsterdam (major Pop-Piano / Vocals). Over the course of 18 years of playing, I've performed on stage extensively -both solo and in multiple bands- written and recorded with many different artists, became a Roland-featured instructor & one of the top-5 Youtube piano teachers of the world and taught over 120,000 people worldwide how to play piano.
Hack the Piano is the backbone-method of all my teaching.
It's the definitive guide to learn how I accomplished all of the above without ever reading a single sheet.
