Historical resonance - Modern freedom

For me, the harmonium is an instrument that builds bridges—it combines the playing characteristics of the organ with those of the accordion. It is an instrument of synthesis, bringing together the keyboard of the organ with the sound aesthetics of reed instruments.

As with the accordion, sound is produced by reeds that are set into vibration by wind. Although you play with both hands on the keys, as on a piano or organ, the bellows allow for direct control. This makes modulation, accents, and dynamics possible, as with the accordion. The tone can be shaped after it is struck, which brings a liveliness to the sound that is lacking in the piano and the classical organ. At the same time, it offers register options similar to those of the organ, allowing for orchestral sound design.

The harmonium in sound and playing style – closer in musical approach to the accordion or bandoneon than to the organ or piano. It shares with reed instruments the intimacy of sound production through wind.

Innovation through improvisation
My musical approach is not traditional harmonium music—which I don't find particularly appealing. Instead, I use the qualities of the instrument for improvisation—including in modern and contemporary styles. In this way, the harmonium—an "old" instrument—is presented and brought closer to contemporary music. It becomes a timeless voice that connects the old with the new and, hopefully, can also inspire young musicians.

My instrument from 1909


Historical masterpiece: Harmonium by Kotykiewicz built in 1909

This exquisite two-manual harmonium by renowned Viennese manufacturer Teofil Kotykiewicz is an impressive testament to the highest level of craftsmanship from the heyday of instrument making.

Instrument details and history

First delivery: April 20, 1909, to Mr. Karl Meyer in Linz on the Danube.
A plaque from the "Klavierhaus A. Merta" piano store in Linz suggests that it was sold through this store. Later, it was privately owned in Upper Austria, from where Mr. Christian Hauf from Bad Harzburg purchased it. Since 2017, it has been in my (Thilo Plaesser) possession.

Technical equipment:
7 Voices
2 Manauals
Percussion (small hammers strike the reeds, producing a bell-like, clearer tone) Prolongement Automat (enables notes in the lower octave to be held down, allowing bass notes to be sustained and the hands to be free).

Sound and quality: A particularly successful instrument

The harmonium is in fantastic original condition and captivates with its extraordinarily lively sound. Its ability to produce dynamic nuances with the bellows is above average and allows for very expressive playing.

Although Kotykiewicz instruments are generally known for their consistently high quality (especially until the mid-1930s), this example stands out. Timbre highlight: Particularly noteworthy are the Harpe Eolienne 2′ (beat) and Baryton 32′ stops, which open up beautiful and rare sound combinations for the player.


The custom-made bench
I subsequently commissioned the accompanying bench to match the style of this historic instrument. It was crafted in a vintage look with milled coves that echo the design of the harmonium's case. The bench is made of 4 cm thick solid beech wood. Only wooden dowels were used, which meant that no screws were needed at all. The front edge of the seat is sanded for optimal comfort!

This harmonium is not only a historical collector's item, but also a fully functional and acoustically outstanding masterpiece of Viennese harmonium craftsmanship.

Research on Teofil Kotykiewicz

My close connection to this instrument motivated me to conduct intensive research: I carried out comprehensive research on Teofil Kotykiewicz, which can be found on the website www.harmoniumfabrik-wien.com I have digitized, researched, and annotated the entire estate of Teofil Kotykiewicz, which is located in the “Vienna Technical Museum“.
