Hi, I'm Koen.
My mission is to prove that beautiful piano improvisation can be learned without sheet music. After 10 years of traditional lessons, I still couldn't play the music I actually loved. Obsessed with film scores from Hans Zimmer and others, I trained myself to play by ear and built the Color Block Method — a simple, pattern-based system for cinematic improvisation. It works best if you already know basic theory.

The 5 F's
Learning is often most effective as a combination of structure and discovery, rather than moving everyone through the exact same fixed steps. Real musical growth rarely happens in a perfectly straight line. Research into how we learn new skills shows that our brains learn best through repetition, emotional engagement, experimentation, and by revisiting and reapplying ideas over time.
Traditional sheet-music education often leaves little room for this. It usually assumes a fixed, linear path where every student has to learn at the same pace and in the same order. My approach is built around how people naturally learn instead: with room to discover, to return to earlier insights, and to experience music in a personal and meaningful way.
Finding Your Way on the Keyboard
Before we play anything, we first find one note: C. Every keyboard is built from the same repeating pattern of black keys, in groups of two and groups of three.
Find a group of two black keys, anywhere on the keyboard. The white key directly to the left of that group is always C.
The white key to the left of every group of two black keys is C.
Finger numbers
On the piano, we don't say "thumb" or "ring finger" — we use numbers. In this book, we'll use just three for now: 1 = Thumb, 2 = Index finger, 5 = Pinky.
Take your time
Today, just practice finding a few different C's on the keyboard. That's the whole page. You don't need to play anything yet.
The Blue Block
We always start with the left hand. That might feel strange if you've had lessons before, but the left hand is where your musical foundation gets built.
Set your hand down
- Find a C, as on the previous page.
- Place your pinky (5) on that C.
- Place your thumb (1) on the C one octave higher.
- Your index finger (2) now naturally lands around the G in between.
Play this loop
Play these four notes, over and over, in this order:
Pinky (C) → Index finger (G) → Thumb (C) → Index finger (G)
This is called the Blue Block. Your hand barely has to move — it just rests in its natural shape. This is deliberately the easiest starting point.
The golden rule: slow
Play at an embarrassingly slow tempo. Like a robot, with every note exactly the same length. Slow is smooth, and smooth eventually becomes fast on its own. There's no prize for speed today.
The Red Block
Once the Blue Block feels easy and comfortable, we'll add one small stretch to turn it into the full Red Block: an 8-note pattern that repeats itself. I use the Red Block in 90% of my music.
The full pattern
C → G → C → G → E → G → C → G
Play the same first four notes as the Blue Block. Then let your thumb (1) reach a little further to the right, above the high C, to play the E, before coming back to finish the pattern.
Common hurdles
- If it feels rushed
- Slow down even more. Your brain and your hand need time to absorb a new movement. There's no such thing as "too slow" while you're learning.
- If your hand feels stretched
- A small amount of stretch is normal. Let your wrist move loosely with the pattern instead of holding it stiff. If anything hurts, stop immediately and try again tomorrow.
Moving It
Once the Red Block feels stable starting from C, that same hand shape can shift to a new starting note. Only the starting key changes — the shape of your hand stays exactly the same.
To play F Blue, for example: place your pinky on the F, your index finger on the C, and your thumb on the F one octave higher.

Shifted to F position
Same shape, a new starting note.
"It's just like going to the gym. On day 1, you start with a lighter weight, and once that feels comfortable, you increase it."
This week
Stick with C Red until it feels smooth and automatic. Once it does, try shifting that same shape to F, using this page as your guide.
The "Staircase Exercise"
This is a small preview of what's ahead. This exercise won't come up until the Red Block is fully on autopilot, but this way you'll already know what's coming.
The Staircase Exercise is a two-hand exercise: your left hand runs a chord progression on autopilot, while your right hand plays a melody made up only of "stable" notes.
This trains your ear and your fingers to feel the difference between notes that sound "at home" and notes that create tension — without reading a single note from paper.
The two golden rules
You may only play stable notes. The moment a note becomes unstable, you resolve it by moving one step to the right — never to the left, never two steps. Because you always step one white key up to become stable again, your right hand literally climbs like a staircase across the keyboard.
"Your left-hand foundation is the walls of your house. The melody in your right hand is the decoration and the furniture. First we build the walls, then we decorate."
For now
You don't need to try this yet. Focus on the Red Block first. This page is here so you know what the next step will be once you're ready for it.
What students say
These students already had basic piano skills. Here's what happened when they learned to improvise with the Color Block Method.
"I had been doing another piano school for a year, but I still couldn't really play anything beyond simple children's stuff. In just a few months, using only a handful of rhythms, I started feeling like I could play along with almost any song."
— Agapito, USA"What I appreciate about your teaching is that you actually slow things down and explain the process step by step. That's the difference for me."
— Pauline, New Zealand"The staircase exercise was the core tool that really made a difference in my playing. It really made a difference and helped me see the notes much more clearly."
— Joseph, USA"I was listening to the radio and I could identify the key of the song, and just start playing along. That had never happened before, not with any app, not with any tutorial."
