The marching French horn is an enigma. Sure, it’s been used by high school marching bands and drum and bugle corps, but there are very few recordings of them on the Internet. They also carry a bad reputation with them…they’re impossible to march with, they sound worse and not as loud as a mellophone, and are generally pointless. Or so people say.

Some of these claims do have some truth to them. Picking out pitches on a Bb or low G single horn with a narrow horn rim while running around a football field is certainly not easy, and the drum corps “Frenchie” lines earned notoriety for lots of cracked notes. The marching horn (regardless of key) also does fall short of the mellophone in terms of raw decibel output. Additionally, band directors often don’t know what to do with them. Do they read Bb parts or F? (The correct answer is F. Always F.) Are they worth the additional expense over a mellophone? Why do some have bent leadpipes and some don’t?

Despite all this, I think the marching horn is unfairly maligned. A good marching horn with the right player and mouthpiece behind it really does sound pretty close to a “real” horn, and you certainly can’t get that sound with a mellophone.

It is also important to understand the marching horn’s integral role in drum corps G bugle hornlines before the legalization of 3 valves. While mid-voice instrumentation in drum corps back then was full of experimentation, French horns were a common choice. Why? Because being twice as long as the G mellophones (or flugelhorns, alto bugles, or meehaphones) meant that they could access many crucial notes in the mid-register that simply did not exist on the other 2-valve alto instruments. This was huge for the arrangers of the time, and a good French horn line added a huge amount of depth and flexibility to a hornline.

However, the top corps had begun to streamline their mid-voice to just mellophones even before 3 valves were legalized in 1990. While the tonal colors of a varied mid-voice line were great, unifying to one type of instrument meant tuning and blend was much easier. That said, a few small French horn lines did survive briefly into the 3 valve era, most notably in the Cavaliers and Santa Clara Vanguard. Both lines used the Kanstul KHB-185 3-valve G French horn bugle, with 8 made for SCV and 6 made for the Cavaliers. It is likely that no other examples of the model were made (despite it remaining in the Kanstul catalog for most of the company’s life), which would mean there are only 14 in the world.

Here’s one!

This is my Kanstul KHB-185, which was one of the Santa Clara Vanguard horns (it is even stamped as such on the bell!). SCV used these only through the 1992 season, after which they moved to all mellophones.

This horn is a great player. It is certainly not point-and-shoot like a mellophone; you have to work for the right notes just like on a single F horn (which is only a whole step lower). But the reward for your efforts is a bell-front instrument that really does sound like a French horn.

But don’t just take my word for it. Here’s a quick 8-part demo I recorded all on this Kanstul:

While the register of drum corps French horn parts meant that they really did not need a third valve, I certainly enjoyed getting to use the full range of the instrument in this bite-sized piece.

Being fully chromatic also means that an instrument like this could really be the solution for playing French horn into a mic that’s placed in front of you. I have played many gigs where I doubled on French horn, and the only solution with a normal horn is to physically turn 90 degrees to the left and hold the bell up the mic like you’re playing Mahler. It is awkward at best. This Kanstul (which sounds like a horn, but points forward) is the perfect solution for a gigging brass doubler. I will not be keeping this specific horn, but I plan to acquire both Bb and high F Kanstul marching horns to see how they fare in the same role. I am much more comfortable improvising in Bb and F, so if those horns sound like this one does we will have a real winner (and one that is much more readily available).

Anyway, here’s a brief trip through some other interesting types of marching French horns.

First up is the Kanstul 285 marching horn in B-flat. While you could be forgiven for thinking that the Kanstul 185 marching horn in G above was based on this, it’s actually the other way around. Zig Kanstul started his company making G bugles only, so this Bb horn is actually a derivative of the G. It has the same up-turned leadpipe to allow for a typical downstream horn embouchure while holding the horn above parallel. Other brands’ marching horns do not have this feature. The B-flat marching horn is the most common type of marching horn, and a few manufacturers (Yamaha, King, Adams) each have a model in their current lineup.

Next up is the Kanstul 284 marching horn in high F. High F marching horns are not commonly known, but they have been produced by Kanstul, Dynasty, and Blessing. Since Kanstul closed up shop in 2019, I don’t believe there are any high F marching horns currently being produced.

There have been some very odd-looking marching horns throughout history as well, such as the Holton MH-100, 101, and 102. These Dr. Seuss horns play as oddly as they look, but at the same time they play concerningly well. They have a trumpet mouthpiece shank for some reason, which allows you to put lots of different kinds of mouthpieces in it. Most inexplicably, they have been copied by Jinbao.

The Low Alto Bugle

Speaking of marching horns with trumpet shanks, Kanstul also made a very odd variant of the KHB-185 3-valve G French horn bugle presented at the beginning of the article. They called it a “Low Alto”, and it is the same as the KHB-185 except for a different leadpipe (trumpet shank) and main tuning slide arrangement. As weird as it is, 6 were built and it did see some drum corps use with the Marauders and later the Kingsmen Alumni.

Because it has a trumpet shank, the low alto bugle can accept many different mouthpiece types. As I have adapters for both trumpet to horn and trumpet to cornet, I was able to see how it sounds with mouthpieces that use all 3 shanks. As it is a Kanstul G marching horn at heart, if you use a horn mouthpiece with an adapter it plays and sounds pretty much like the KHB-185 French horn bugle. It’s a little harder to play accurately and a little more work to get a centered horn sound (I suspect mostly due to the adapter), but it’s there if you work for it. And unlike the 185, the low alto has a whole toy chest of other sounds to explore by using different mouthpieces.

From my time with the low alto, I found that horn, tenor horn, alto trumpet, and very small trombone mouthpieces worked the best. I do think that a mouthpiece that truly matched the instrument well would have to be custom made. But rather than talking about it any longer, I’ll just let you listen. I recorded a small collection of short, improvised excerpts on 11 different mouthpieces (and adapters when required), each meant for a different instrument.

Lastly, here’s a back-to-back comparison of the 2 marching horns with trumpet shanks: the G low alto bugle with horn mouthpiece (via adapter) and the Holton MH-101 with horn mouthpiece (via adapter).
