Concerto Jubileo 40

The Content Concerto Jubileo 40 is an organ built in celebration of the 40th anniversary of Content Organs in 2020. The organ is equipped with a high-quality Kienle pipe-resonance system. This means that there is a speaker under each pipe, closely approximating the sound of a real pipe organ. In essence, this is a 'digital pipe organ.' The organ is located in the concert hall of Content Organs in Ermelo.

This organ is available in all color variations!

Selecting stops


'My organ is my orchestra' is a well-known saying by the French organist and composer Cesar Franck. More fittingly, the art of registration cannot be summarized. An organ consists of foundation stops (prestants and flutes), compound stops (Mixtuur, Scherp, etc.), and reed stops (Trompet, Vox Humana, Bazuin). Various stops can also be used individually as solo stops. Well-known solo stops on Dutch organs include the Cornet, Vox Humana, Trompet, or Sesquialter. On the Content Concerto, you can find these stops. Discover the richness of possibilities and tonal colors of the ancient pipe organ!

How does a pipe organ work?

A pipe organ consists of numerous pipes, each with its own sound, often imitating musical instruments such as a trumpet, flute, or oboe. There are also voices unique to the organ, such as the principals and octaves. By pulling stops, the organist can select which organ pipes to use. When the organist presses a key after pulling a stop, a mechanism ensures that air from the wind supply flows into one or more pipes. Depending on the size, shape, and material of the pipes, a wide variety of sounds can be produced. Principals produce a resonant tone, while flutes sound mellower. Mixtures (small, short pipes) produce high and bright tones, while a 16' trumpet sounds low and dark because this stop consists of long, wide pipes. What makes the sound unique is the way it resonates in the pipes, each with a different length, altering the pitch. This principle is also utilized in our Kienle® pipe systems.

What are Kienle® systems?

The German organ builder Ewald Kienle (1928-2022) found the solution for the long-desired combination of digital organ sounds with the resonance of an organ pipe. Through the use of advanced speakers, where each speaker finds 'amplification' in a real organ pipe, authentic organ pipe sounds are produced. With this modern, patented technology, the process of sound development in the pipes can be controlled very precisely and reliably. The organ pipe sound system is, therefore, the optimal solution for desired high sound requirements, even under challenging temperature conditions.
