The new and improved flag of Pocatello, Idaho, formerly the "worst flag in the United States"

The Stroh Violin by Sean Real

In the late 1800s, people were just starting to consume recorded music, and the process of recording at the time was quite hectic. Before microphones and studios, sound was captured by big horns, which were made mainly of brass or copper.

Recording horns would collect and focus sound vibrations into a diaphragm, which would then vibrate a stylus that cut a groove into a wax disc. But these devices were limited in terms of the sound frequencies they could capture. Brass instruments like tubas and French horns would get picked up much better (and ultimately sound louder) than string instruments like guitars and violins.

These days, different instruments are recorded on different tracks, and a lot of leveling is done after the fact. But back then, they had to record whole orchestras with just one or two recording horns in the room. Then they would make direct copies of the original recorded disc to distribute.

Effectively, there was no editing. If the French horn was too loud, or an opera singer blew out the recording with their falsetto, the disc was discarded and recording started again.

In order to get a balanced mix of different instruments and voices, sound engineers would arrange the musicians all around the studio at various distances from the recording horns. Sometimes they would have the louder instruments pointed at the back wall, away from the recording horn, the musicians watching their conductor in a mirror. They would put pianos on top of platforms so that the mallets and chords inside would be lined up with the recording horn. In some cases, they would even put a singer on a little trolley so that an assistant could wheel them closer to the horn for quieter vocal passages and wheel them away during louder ones. But string instruments were the hardest to record, so, stand-up bass parts were often played on tuba instead. And a lot of engineers didn’t want to deal with recording violins at all, so they left those out.

 

Then, in 1899, John Matthias Augustus Stroh invented a violin to address the limited frequency range of recording horns.

The horn on this Stroh violin amplified the frequencies that were more resonant in the recording horns, so violin parts would come in clearer on the recordings — it was a kind of de facto equalization device. The horns on these instruments were also made to be louder and more directional so that they could be pointed straight at the recording horn.

At the time, this was a big deal for the recording industry. The design was applied to all kinds of string instruments: Stroh guitars, Stroh cellos, Stroh mandolins, Stroh ukuleles. And there were articles that speculated about where the Stroh was ushering in a new kind of music.

From a Strand Magazine article published in 1902: “The harmonics are loud and pure, and what is of great importance is an entire absence of ‘scrape.’ This is a point that solo-players will value highly.”

Then, in the mid-1920s, electric microphone technology began to make its way into recording studios, and broader ranges of instruments became more possible to capture. These modified instruments no longer made the same kind of practical sense, so the Stroh Violin Company slowed production and then finally shut down in 1942.

In hindsight, it is easy to dismiss them as a fad, but without the Stroh a lot of early records wouldn’t have featured violins. And some are still in use today, played by folk musicians in places like Romania and Myanmar. Singer-songwriter Shakira had a Stroh player along on her 2010-2011 tour, as seen in the video above.

The Stroh approach has left a legacy in terms of contemporary instrument design as well — resonator guitars use similar technology. In fact, one of the inventors of the resonator guitar visited the Stroh Violin Company’s factory in its heyday, and there are a number of articles that suggest he based his designs off what he encountered there.

    My favorite image of the flour sack prints is from Life Magazine. In the image there is a pile of Sunbonnet Sue flour sacks in assorted prints, but the worker is filling one with a stuffed bunny sewing pattern on it. I like to think that even in times of scarcity and rationing that someone’s little girl, who came with her mother to the general store pleaded for that flour sack like my little girl asks for stuffed animals… well everywhere. I hope she got it.

  2. Ice wasn’t the only material they experimented with for shipbuilding in WWII. Look up the concrete ships. There’s the wreck of one just off a beach in NJ.

    The story of the Stroh violin was fascinating especially as it has a strange connection for me. I am from Northern Ireland and in the capital city, Belfast, there is a well known Romanian busker that uses what I now know to be a Romanian horn violin. This morning I was talking to my work colleagues about the busker, wondering what the strange instrument was. A couple of hours later I listened to this podcast and to my amazement, I could not believe that this podcast contained the answer to our earlier conversation and that the instrument was one of the subjects in the podcast! I just cant believe it, what are the chances!

    I’m a big fan of the show and never miss a podcast, I particularly like these mini stories episodes, especially when you come up with fascinating and interconnected stories like this!

      Yes, I came to the site for the same reason, hoping to see the old and new flags!

    I once found a portal into an interdimensional vomitorium when visiting Pocatello. I saw some unexplainable entities there who were really into eating pawpaws.

  5. Great story!!! Funny fact I round researching this story: the man who patented the idea was named ‘Bales’. :) There are some really good books about this, including one called ‘Feedsack Secrets’. Question: is anything known about the designers of the patterns?

    The admiral who came up with the ship idea was named Mountbatten. Was he in any way related to Prince Philip? I was just wondering. Thanks!

      I was (even as an American) a bit vexed when a member of Prince Phillip’s family and mentor to Prince Charles was only described as this one admiral. There was even the loss of an additional mini story in the deal. Mountbatten was a design choice to Anglicize a Germanic name (maybe a bit of a stretch), the name was chosen to obfuscate the family’s German heritage during WWI by translating the parts of the name separately and smashing them back together.
