If you enter any surviving early 20th-century Belgian dance hall, there’s a good chance you’ll be in front of something that once performed the tasks of an entire orchestra loudly, mechanically, with a theatrical excess that seems almost ridiculous today. The dance organ was more than just an instrument, especially those manufactured by the Antwerp-based company Mortier. It was an occasion.
The majority of European cultural obsessions appear to have their roots in Paris, where the story of the dance organ starts. The first large instruments were created by Gavioli and Marenghi to fill ballrooms without the need for a bandleader, a union contract, or a single musician to arrive on time. They were mechanical devices designed specifically to induce dancing.
However, Mortier began doing something different at some point in the early 1910s. Instead of mimicking what a small orchestra might play, they started creating instruments that could follow the trends of popular music, such as jazz, foxtrot, big band, and eventually Latin rhythms. They did this by adding percussion and expanding the pipework, constantly changing the sound schemes to fit whatever was playing on the dance floors at the time.
Perhaps no other instrument in European history has undergone such a relentless evolution in response to popular taste. The majority of instruments are stationary items. A piano is just that a piano. The popularity of ragtime does not cause a violin to grow a new string.
In contrast, the dance organ was nearly always upgraded, sometimes completely rebuilt, to keep up with the latest trends. Mortier regularly updated older Gavioli and Marenghi instruments in the middle of their lives, much like a car getting a new engine. Even though it begs the question of what the original instrument was intended to be in the first place, there is something commendable about that.
By the early 1920s, Mortier was the most well-known brand in the industry, with Gaudin of Paris coming in second. Almost exactly, Art Nouveau facades gave way to the crisper geometric lines of Art Deco as the decade progressed. In addition to producing music, the instruments were made to appear authentic to the time period.
When you watch one today in a museum or a renovated café, you get the impression that the people who created them had a deep understanding of the connection between dance and spectacle. The façade was important. The lights were important. One aspect of the experience was the machine’s actual physical presence.
Because they demonstrate how seriously these builders took their craft, the percussion capabilities are worth considering. Early instruments used pipework appropriate for ballroom elegance to handle the formal dances of the Belle Époque, such as the polka and two-step waltz.
By the late 1910s, jazz was pushing music toward an entirely new vocabulary of rhythms, which the organs adopted. There were xylophones. Lengthy passages with percussion. Latin American rhythms eventually needed another round of mechanical adaptation in the 1930s. The idea of a machine constructed in Antwerp and subtly modified year after year to play the mambo is still somewhat astounding.
The robot bands that Decap of Antwerp created in the early 1950s may be the pinnacle of all this ambition. In all, seven were produced. Each had three articulated robots: a brass instrument, a saxophone, and a percussion instrument.
In fact, the robot drummer rotated his head to line up with various drums. When performing, the wind players would stand with their shoulders shifting and their cheeks expanding to suggest breath. They bowed at the conclusion of a music roll. It’s hard to say whether this is engineering or theater, but it’s clear that the distinction between the two was never important. The idea was for people to pause and look around the hall.
Mortier’s legacy is linked to a specific period in European social history, spanning decades between the wars, when public dancing was truly mass entertainment. On a Tuesday night, a dance hall in Brussels or Amsterdam could be packed for the majority of regular people; the organ in the corner was the closest thing to a live band.
Following World War II, popular music shifted toward electronics; the dance organ followed suit. Traditional pipework was somewhat awkwardly replaced by Hammond tone generators; the outdated mechanical logic found it difficult to adapt to a world with turntables and amplifiers. Although its period of supremacy was over, it never completely vanished.
A few manufacturers still produce dance organs today that use MIDI and Wi-Fi to create digitally generated tones. Depending on how attached you are to the original concept, this may or may not be considered irony or continuity.
What is evident, however, is that the Mortier organ’s eccentric, costly, constantly updated, almost theatrically ambitious design accurately reflected how Europeans desired to spend their evenings over a remarkable fifty years. They desired nonstop music. A machine that never reported illness. Dancing that might continue until the building was shut down.
