DODEKA, the revolutionary music system

[Josua Rochat]

Dear all,

Let me introduce DODEKA. Created since 1980 by Jacques-Daniel Rochat, DODEKA is a revolutionary music system that simplifies composing and playing music. Based on a chromatic approach, the new system introduces a new staff, composed of four lines, and a revolutionary keyboard, on which all keys are set at the same level. With this system, sheet music and keyboards work in synergy as there is a direct relationship between the structure of the staff and the key's arrangement of the keyboard. The system works with every instruments and is accessible to everyone.

Watch our new video to learn more about our great system and visit our website http://www.dodeka.info

For any other question, don't hesitate to contact me directly. I'll be happy to help.

Cheers!

Hi, Josua

For me Dodeka is still too complicated.

[Joseph Austin]

I'm especially curious about the keyboard.

Are these for sale?  How much?

Can it be played without looking? Can you find position by feel?

Re notation: 

How do you represent timing? Chords? 

(It would seem there would be collisions between notes of chords, obscuring the pitch.)

Had you considered orienting the staff with lines vertical?

That would make it even more intuitive.

Have you developed a beginner method for the notation and keyboard?

Do you have software for creating/editing scores, or converting MIDI, etc. to your notation?

PS,

Sorry for the elementary questions; on first look I missed the notation section of the website.

I'm thinking this notation is quite close to "piano-roll" notation, or SynthesiaGame.  All you need is to add a staff, maybe color.

It should be straight-forward to create from a MIDI file,

I think the different colors for the lines and keys would be a useful addition to the notation in any event.

Hi Joshua,

I echo Joe's questions; is a keyboard available, and is there software to create Dodeka scores?

And also: is sheet music available? 

How does Dodeka rhythm notation function in more complex music in which voices do not follow the same rhythm?

The video is nicely produced, however I miss a few shots with sound of people actually playing the keyboard.

How was the keyboard in the video adapted, and would it be easy to do so for anyone?

Hi, Josua. 

Great thing that you are taking this step to make DODEKA commercially viable. The design of just equal keys one next to the other always seemed to me like an obvious great design for an instrument, but, to my surprise, you were the only ones focusing on this at the time I first started looking for a keyboard like this, and I think you still are (there is haken continuum, but I think they stumbled upon that design by chance, and don't seem to realize it's potential). 

By the way, I am the 'Fernando Terra' you used in the "See what other people say" section of your site. 

What's the price of the keyboard?

Does it ship to Brazil?

Anyway, I wish you luck on the enterprise. Hope you succeed.

I've mentioned it before on this forum, but it might be worth repeating that this kind of keyboard design predates DODEKA. For example, here is a patent by John Robbins, filed in 1949:
https://www.google.com/patents/US2627777

The Robbins/DODEKA layout is conceptually the simplest isomorphic layout, but it might not be the simplest from a practical, ergonomic point of view. Paul Vandervoort, who is likely the most experienced player of Janko-style keyboards, initially started out by building a Robbins/DODEKA-like piano keyboard before concluding that it was too difficult to play and that the Janko layout was superior.

Hi Joe, Willem and Doug,

 

The Rochat have made attempts in the past to have scores produced through Musescore, but without succes. Read those posts

from 2009: https://musescore.org/en/node/735 they are self explanatory. Dominique

Hey Joe,

Thanks very much for your messages and all your questions. I think that our website answered a few of them. I will mainly focus on the ones about the keyboard and the software.

Currently, we don't have any piano/keyboard for sale. Yet, we will shortly launch a fundraising campaign (around September) in this perspective, as creating pianos/keyboards is somewhat capital intensive as you may know. We hope to be able to sell different kind of keyboards around the end of the year. In terms of price, the DODEKA keyboard shouldn't too pricy, certainly more expensive than traditional keyboards, since we are taking about few models, but fair prices.

Regarding the software for creating sheet music, we have contacted and met several organisations that are capable of doing such a software. Like the keyboard, we would like to offer the software by the end of the year/beginning of next year.

So, for now, we seek to make this great music system known. So, if you like it please feel free to share it among your friends.

Finally, Joe I have one question for you. If at the end of the year or beginning of next year we have piano ready for sale, would you buy one?

Cheers,

Josua Rochat

PS. for the beginner method please refer to adaptable keyboards' section (learner score and colours) on the website and keyboard. And, yes displaying the staff vertically is also one of our idea for our software.

[Josua Rochat]

Hey Willem,

About the software and sheet music, please refer to my last post.

For musical composition with two different rhythm, do you have specific examples? I'm not sure to understand what you meant.

The keyboard on the video was created by my father in his spare time. I'd like to say that it is relatively easy, if you have time and some skills in engineering/mechanics.

Currently, two guys have been building their own DODEKA's keyboard. So, yes clearly possible.

Really happy to know that you like our video.

Cheers,

Josua

Hey Doug,

Thanks for your remarks. Yes, you are totally right. J. Robbins filed a patent for an isomorphic type of keyboard.

Yet, DODEKA isn't just a keyboard. It is also, and mostly I'd say, a logic notational system that works with every instrument. The notational system and the keyboard work together, as there is a direct relationship between the sheet music and the layout of the keyboard. And those two elements combined make reading music and playing the piano very easy. Personally, I've started to play the piano with DODEKA since March 2016. And, after less than a day, I was able to understand the basis of DODEKA. Now, I can read and play every musical composition. I just need more practice to be able to play more fluently.

Cheers,

Josua Rochat,

Ps. The video (around 2:47) illustrates particularly well the direct relationship between the DODEKA staff and the layout of the keyboard. It is worth a look.

[Josua Rochat]

Dominique,

Thanks for your message. I'm not sure if I got your point. But, we are currently in contact with companies that see not problem in creating such a kind of software. Even the person from Musescore said that it was possible: "My conclusion is that, although certainly feasible, the effort required would be too much for me". As I said in my previous post, we will try to offer a software compatible with DODEKA by the end of the year/beginning of next year. It will mainly depend on our capacity to raise funds.

Cheers,

Josua
