Instruments
Kaduk develops instruments as systems for musicians, designed around playability, physical position, and musical control.
Our instrument lines are defined by the problem they are meant to solve — not by historical categories or conventional market segments.
We work in three lines: Fundament, Individu, and Tendens.
Fundament - Coming Soon
Fundament is a preparatory instrument designed to form correct technique from the start.
It prioritises physical position, clarity of touch, and consistency — the elements that shape a pianist long before sound projection becomes relevant.
​
Fundament prepares pupils for the instruments of the future, not for legacy pianos built around historical constraints.
Its modular design allows the keyboard to be used independently for practice and study, while remaining part of a complete instrument when sound production is required.
​
This line exists because early training should develop transferable skill, healthy habits, and musical awareness — not adaptation to compromised instruments.
Individu
Individu is Kaduk’s feasible, practical workhorse line, developed as a full-scale professional instrument for real-world use. It is designed for musicians engaged in serious artistic work, where reliability, serviceability, and consistency are essential.
​
Portability is a cornerstone of the Individu line. Within the class of concert-capable instruments, Individu is designed to be transported and set up with exceptional ease, allowing it to move between studio, teaching, rehearsal, recording, and concert environments without dependence on specialised infrastructure.
​
Within the Individu line, models range from intimate contexts to fully concert-capable instruments.
Even in its most practical configurations, Individu remains fully viable on stage — prioritising usability and reliability over monumentality, while retaining authority and projection where it matters.
Tendens
Tendens represents the pinnacle of Kaduk’s instrument development — the most refined, capable, and complete expression of our work in pianistic and acoustic terms.
​
These instruments are developed to offer an exceptionally direct, smooth, and controlled playing experience, paired with a long, open, and singing tone that remains clear and articulate across the full dynamic range.
Tendens is built to sustain large spaces, extended musical forms, and the highest demands of professional performance without loss of nuance or control. Tendens surpasses all regular acoustic instruments in almost all fields.
​
Tendens instruments function as portable concert grands.
Even in their largest configurations, they remain transportable by normal people using regular vehicles — a level of practicality unheard of in traditional concert instruments, without compromising authority or presence.
​
The Tendens line also forms a coherent ecosystem.
Variants such as Tendens pro Intimi extend the same instrument into the home or studio, allowing pianists to work on the identical keyboard and action, and connect to the concert soundboard when performing.
This continuity eliminates the gap between practice and performance that defines conventional piano culture.
Beyond performance, Tendens carries a deliberate sense of prestige and refinement.
Its design, materials, and construction reflect the seriousness of the instrument — not as decoration, but as an expression of clarity, precision, and intent.
​
Tendens exists where no compromise is acceptable:
maximum musical authority, uncompromised playability, and concert-scale open sound — delivered in a form that remains usable, transportable, and controlled.
