What we do
We create custom high quality music instruments of any kind - be it acoustic, electric, or digital - on demand. Also, we modify your existing instrument to your needs whilst respecting its identity. For better performance, ergonomics, or both we produce standardized but custom made (grand) piano interfaces consisting of keyboard and action.

What we stand for

We stand for a future of artistic musicians. We believe in aesthetics and science as well as in meaningful communication. We want to take a relevant position in the upcoming transformation of the music scene, consolidating on understanding, joy, health, cooperation, and musical expression.
A sculpture in time - In dialogue with your audience
We believe that music is a sculpture in time in which the musician removes all fragments that do not fit into the expression of his meaning - as a sculptor does in stone. Yet, haven't we all experienced music as the most direct form of art? Penetrating directly to the soul it doesn't need words as symbols. Ideally, live music is a dialogue between artist and audience, as well as between the conscious and the unconscious. In its optimal form this dialogue assists its participants to discover what is relevant in life.
The perfect instrument, the perfect match - In dialogue with your instrument
Each of our instruments is rich of character, yet transparent in contact and approach, offering a wide array of nuances to play with. This balance of character and transparency causes our instruments to be easy to move, but hard to master, which makes it joyfully interesting to play. In dialogue with the instrument, a broad range of possibilities opens up, and together you create music out of sound.
Play, and we will listen - In dialogue with the maker
From concept to production we connect different fields of the sciences and the humanities. With access to modern and diverse professional production facilities we make choices solely based on knowledge and understanding, not shying away from advanced fighter jet technology. Implementing the most advanced research and production technologies to date is exactly what the great piano builders from the 1880's till the 1920's did. We believe in their approach and follow the tradition they set.
The modular piano
Make your piano modular. Start with the interface, which consists of a keyboard and an action. We offer easily switchable piano interfaces in different qualities, sizes, and layouts for different instruments and for different needs. We offer the keyboard in any size in a traditional piano layout, and we also offer Janko layout or improved Janko layout. All interfaces/keyboards are custom made to fit your instrument and you. We can build one for you on basis of the following series:
Custom instrument
We can build any custom music instrument or modify your existing one. These are our favourite projects, so never hesitate to contact us if you have the slightest wish. We help you to discover the possibilities. If desired, we can start a trajectory realising your musical dream and build your new grand piano, violin, or other dream instrument, or maybe just modify your favourite analogue synthesizer?

Basic scientific principles of playing a piano key
Let's just start with a very basic explanation of the parameters that are relevant. A piano key has zero momentum in rest. Momentum is the product of mass and velocity. Thus when the velocity is zero, it doesn't matter what the mass is, the momentum is still zero.

Then there is force. Force = mass times acceleration. This is Newton's second law. If a certain force is applied, and the mass is higher, then the acceleration is lower.

The pianist applies a certain force into the key over a certain time. The pianist thus creates a so called impulse. So if you have a graph of force and time, then the area underneath it is the impulse. Impulse is what changes momentum, thus what changes the motion of the mass (or the mass, but that is in this case not possible). Impulse thus is not the same as the momentum, but it is equal to the change in momentum that is given to the system. To create an impulse or to change the momentum work is needed.

Chemical energy from our food is transferred to kinetic energy by the so called work of the pianist. Work is what transfers energy from one form to another one. Work here is force times distance. When the action is moving it has kinetic energy, equal to the work done by the pianist. For the energy of the system the speed is way more relevant then the mass, since the amount of kinetic energy is only 1/2 times the mass times the speed square, Ek=1/2mv^2. The momentum divided by the mass is the velocity (momentum = mass x velocity --> velocity = momentum/mass). So if we use momentum divided by mass instead of v in the formula of kinetic energy you get 1/2mass(momentum/mass)^2=momentum^2/ 2 times mass. In this formula you can easily see the counter-intuitive relationship between momentum and kinetic energy. You can see that a system with the exact same momentum, but less mass caries more kinetic energy. I say that again: If a heavy system and a light system have the same momentum, the light system has way more energy.

When the key is played, the pianist uses a certain amount of energy to create the work that generates the impulse that creates a momentum in the piano key. Momentum is always conserved (about friction I can explain later). So moving mass times velocity at the beginning is moving mass times velocity at the end. Thus the moving air mass, of which we interpret the propagation of the disturbance it caused in the medium - air - as sound, has the same momentum as the fingertip striking the key.

Before the airwaves move through the room a series of so called inelastic collisions occur already in the piano action. An elastic collision is a collision of objects in which all kinetic energy is conserved. An approximation of that can be seen when one billiard ball stops completely when hitting the second that instantly gains the speed of the first. An inelastic collision is one in which a part of the kinetic energy is transferred into internal energy. Usually this so called internal energy is still kinetic energy on the molecular scale. The first molecule hits the second, starting a wave of molecular collisions, and that we call thermal energy or heat. Then there is also a perfectly inelastic collision possible in which the bodies are bonded together. This does not mean however that the newly combined body doesn't move. It moves because of the conservation of momentum.

In the piano the collisions are very inelastic; i do not say perfectly inelastic. A substantial amount of kinetic energy dissipates into the system as internal energy. Moving as waves through the materials, like usually ivory, wood, felt, metal.
