I am Dutch too by the way, I was just Googling on Klavarskribo and hit this blog.
And a very interesting blog it is!

I have always loved piano’s and music. So at age 12 I took piano lessons. I was thrilled, finally I would be able to decipher those notes on paper and play them too! But soon I found out that reading music just wasn’t for me. When the lessons started I could manage to ‘read’ it but as soon as the music started to get more complicated I just couldn’t ‘get’ it anymore.

I sort of ‘blocked’ when the score turned ‘too busy’ because of the notation mess that was created a long time ago. I was stumped that music was written down in such a complicated way, so many things to remember (like key signatures) and it caused me to feel quite rebellious too. I struggled for years, getting to hate my piano and teacher. She must have thought I was really stupid!
So at 16, after four years of struggling I quit playing the piano. The fun and love for the piano was completely gone.

Several years ago at age 45 I bought an old piano in a wave of hope that certainly now as an adult I would certainly ‘get’ it! I turned out to be a fast learner at college and in my profession, so what could be the problem!
I bought all kinds of books to learn how to read music. Took lessons.. but no avail. I STILL couldn’t manage!

Then a few years ago my stepmother died, and in her belongings was a course Klavarskribo dated 1953. It was on very old fashioned faint beige paper printed ‘old typewriter style’ with brown ink. I started lesson number 1 and boy.. I went through the lessons like there was no tomorrow! At last I was able to read and play!! I sucked it all op like a sponge

I wish I had known Klavar when I started playing when I was young, I missed out years of fun owning a piano, practice and I would have been a much better player now. A pity, really!

And I am not the only one.. through the years I met several people (IRL an on the internet) who experienced the same ‘blocking’ when old style (yes I call it OLD style) music gets complicated. I would really like to know what it is that some folks just get blocked reading old style music.

I read several overheated discussions on pianoforums about other notations (like Klavar), and noticed people get really irritated by the idea that someone had the nerve to develop other notation systems, as their old system is holy ánd the best. They learned it, so can you. :/

I especially like how you changed the perspective on the keyboard, using a front-on view. That makes the mapping even more obvious. Just out of curiosity, I wonder how Klavar would look if it used squares instead of circles.

I arrived here while searching for the Mirck version of Klavarskribo from Mrs Mirck.
I am the person responsible for the http://www.klavarscore.co.uk website.
Thank you for subscribing to the newsletter.
I am sorry to say that, as you can see from the home page of the website, the project had to be put on stand-by. The comment from Mr Fons Doomen in a post above, “… Klavarskribo Foundation, the remains of the once very big Institute founded by Cor Pot…” says it all.
I invested reasonable figures in time and money, together with other generous investors, to re-vitalise the activities of the Foundation and give them a “vision for the future”. After three months of meetings and attempts, I had to throw the towel.
I have the possibility to create a catalogue of music in any easy-to-read notation, either klavarskribo or another, and I would welcome any suggestion.
I welcome the Mirck modifications to Pot’s notation; however, the fact that the klavarskribo notation doesn’t score very well on the musicnotation.org website stops worries me a bit. Their requirement 13 prevents Pot’s klavarskribo to qualify and I would be grateful for any explanation on how Mrs Mirck’s version is mentioned. Is it perhaps because of the horizontal staff?

I subscribed to the newsletter too. Thanks again, Evan
