I’m guessing a lot of orchestras are putting together their spring/summer concert series. A few of them will be performing “An American In Paris” and are looking for sets of tuned horns. Especially following the more recent discovery of the 1929 version pitches. Happy to say I’m having some success at helping folks out. Still more of an art and I hope to be making my own reeds sometime this year but…
May 2024. A Gershwin set I put together for the Greensboro Symphony…
From the David and the Richmond Philharmonic.
The horns were perfect. It took a bit of work on the highest horn, but the concert went without a hitch. Please feel free to use that video!
What I ended up doing was marking the reed with a sharpie on both sides on the correct placement of the zip tie. They moved after a number of honks in rehearsal, so I ended up resetting them each session.
It’s happening! Very excited to report that the set of Gershwin horns I put together have found a home and will be used in a production of American in Paris in the next few months. I will definitely be updating with hopefully some video then. David sent me this image of his mounted set of horns. Ready for rehearsals!
I’ve been trying to put a set of Gershwin’s ‘American In Paris’ (1929) taxi horns together. I’ve been doing a lot of experimenting with tuning the reeds. What I really need to be doing is making my own. At some point I will. In the meantime this is about as far as I’ve been able to get so far. Some of the reeds in the video have been manipulated by sliding a zip tie down the length of the reed. Problem there is each reed will only take so much manipulation before it stops vibrating. I’ve seen things like the tuning change a bit from one day to the next… Weather? Zip tie expanding? If you’re willing to work with me, and not be too fussy over the exact pitches, I can put a set together for you. Contact me john@squeezehorns.com to discuss. (Larger version video here.)
Tuning a horn. It’s an art not a science (yet).
I thought to include this video for comparison. The pitches in this performance don’t correspond to either of the versions we’re used to, but in the end it’s more about the effect. I don’t know, but my sense is that that is what George was going for in the first place. (An American In Paris Percussion Frank Lao)
Well known for its use in Gershwin’s ‘An American in Paris’, I realized today I had no idea what in fact a ‘taxi horn’ was! If you Google it you’ll just get references to Gershwin, especially since the discovery that ‘we were doing it wrong’. (See my post here.) Consider that the horns Gershwin used were NOT what you’d typically find installed on an automobile by the manufacturer. (See vintage auto ‘bulb horns’, including many from French manufacturers here.) So what were they?
I turned to Google Books, sorted by date, and looked for references to ‘taxi horns’ from the early 1900s. Gershwin wrote ‘An American in Paris’ in 1928, and the thinking behind using taxi horns in the composition was to evoke the ambience of Paris.
Here’s what I think… In the 1920s, taxi drivers, especially in France, would sound a ‘taxi horn’ when arriving to pick up their fare.
The ‘rattle of wheels’ sounds to me like it could be a carriage.

About now (1940) the term is becoming ambiguous. This could certainly be a taxi’s horn, rather than a ‘taxi horn’. 
But maybe you know better, or have something to add. Feel free to leave us a comment. Thanks!
University of Michigan has a 2016 video describing the original taxi horn tones of the Gershwin score. [Updated 11/19 See also new Taxi Horns post.]
Reader Jan (see comment below) shares an insight into the notes used in the original recording. That lead to this article (lots of interesting details): 1929 Gershwin Taxi Horn Photo Clarifies Mystery. It would seem the mystery of the actual tones used in the original recording is solved!
A comment from Bill Schuetter today provided the missing clue to discovering a source for tuned squeeze horns. Bill provided a link to a YouTube video of the LA Philharmonic performing Gershwin’s ‘American In Paris’. There they are! and certainly orchestras around the world would need these to perform Gershwin. I found a few sources. See links below.
[Update 5/11/15] There you go! Owner Russ Knutson, of Chicago Percussion Rental comments below to point out that the horns in this shot came from his shop.
Certainly not cheap to purchase. That’s about $750. U.S. From Kolberg in Germany.
Most orchestras rent the set of horns. In the U.S. often from Steve Weiss Music outside of Philadelphia.
Also from LA Percussion Rentals. FSTJ Percussion in Quebec, Canada.
