“Alto bugle” typically refers to a type of competition bugle pitched in G for use in drum and bugle corps. Of the four main types of mid-voice bugle used in drum corps history (mellophone, French horn, alto, flugelhorn), the alto bugle is probably the rarest type. Usually based on a G mellophone bugle but with a much smaller bell, they didn’t make a lasting impression on the field. However, they offer intriguing possibilities for use outside of drum corps as they are essentially big flugelhorns in G. (There were actual G flugelhorns in DCI as well, but those were generally standard B-flat flugelhorns with tubing added.)

Many alto bugles had 2 valves, as that was the rule in DCI until 1990. But there are a few models of 3-valve alto bugle that exist. These are as follows:

Dynasty III alto bugle (late 1970s): Likely the earliest 3-valve alto bugle to be made. As DCI was over a decade away from legalizing 3 valves, the complete Dynasty III bugle line was made (mostly by Willson) for the European market. Surviving examples of any type of Dynasty III bugle are extremely rare today.
Dynasty late-pattern alto bugle: This one was based on Dynasty’s existing mellophone design rather than a separate one, and was made in-house instead of by Willson. (The link calls it a flugelhorn bugle, but the Dynasty 3-valve flugelhorn bugle was a different beast made by slapping longer slides on a DEG Signature 2000 Bb flugel.)
Kanstul KAB-175 (‘90s, early model): This early model Kanstul alto bugle design resembles a smaller King 1120 marching mellophone, and as both instruments were designed by Zig Kanstul, is probably where the King design originated.
Kanstul 175 (late model): The later model used a totally new wrap and was made until Kanstul went out of business in 2019.

At one time I owned the only Dynasty III alto bugle I have ever seen. I haven’t been able to find any record of another individual example on the Internet. As none were made for the US domestic market, it may be the only one in the country. But rare G bugles have a funny tendency to show up in the weirdest places, so there could be others hiding in the States. I bought mine from Canada.

The following picture shows the Dynasty III, and also my DEG 1220 alto cornet in F for comparison, also made by Willson around the same timeframe and also very rare (but much more common than the Dynasty III!). It’s easy to see the family resemblance between the two instruments, even though they actually sound quite different.

Dynasty III G alto bugle (left) and DEG 1220 F alto cornet (right)

As the names imply, the alto bugle sounds like a flugelhorn, while the alto cornet sounds like a cornet. The alto bugle has a fat, dark flugel sound; the alto cornet has a brighter, leaner cornet sound. Both instruments play very well.

I also used to own an early pattern Kanstul KAB-175.

This instrument had a fabulous flugelhorn sound with a tenor horn mouthpiece (the same one I used in the Dynasty alto bugle and alto cornet). It was smoother and a shade darker than the Dynasty, and was a really refined sound. Which is not to say the Dynasty was rough; compared back to back with my Couesnon flugelhorn the Dynasty sounded quite close, just with a bit more beef in the sound. But the Kanstul took it a step further and makes the sound a little rounder and sweeter still.

Unfortunately, with this mouthpiece the instrument also played quite flat with the tuning slide all the way in. This is likely because it was designed around the classic Mello 6 marching mellophone mouthpiece. I have one of those, and putting either it or my Hammond 5MP marching mello piece into the Kanstul fixed the pitch and felt like the right match for the horn size-wise…but also entirely lost that lovely velvet flugelhorn sound. With the Mello 6 it predictably sounded like a more focused, direct marching mellophone. Very bright and trumpety, but much fatter than any trumpet (or G soprano bugle). There may be a niche for this sound, but I couldn’t find it and the big flugelhorn sound is really what I want in an alto bugle, so I eventually sold this instrument.

Physically, the Kanstul was fantastic. The valves were the best I’ve ever owned in any kind of brass instrument…lightning fast and whisper quiet. The instrument itself felt like it weighed nothing in the hand, owning to its light weight and great balance. I’m sure it would be a pleasure to march with, as instant horn snaps and moves are a piece of cake. The left hand grip is comfortable, there is a 1st valve slide kicker…it has everything you want. It feels like a massive leap forward in alto bugle design from the Dynasty, although the Dynasty’s super-compact form factor is definitely convenient. It is a shame then that the Kanstul doesn’t work out of the box with the tenor horn mouthpiece that the Dynasty happily accepts without issue; it could be that that early alto design was based around a larger, more tenor horn-like mouthpiece.

Although I never found a real use for the Kanstul and thus sold it, it’s one of the most enjoyable brass instruments I’ve ever played and I do miss it.

The Marching Alto

Just as the mellophone bugle in G begat the marching mellophone in F, the alto bugle in G begat the marching alto in F. And as rare as the G alto bugle is, the F marching alto might be even rarer. Unlike the alto bugle and its limited use in DCI drum corps (especially in the 2-valve era), I know of nobody who ever fielded a line of marching altos. (If your high school or university marching band did, I’d love to know about it!)

These are the types of marching alto I know of:

Kanstul KMA-275 (late model): This is the F version of the late-pattern 175 alto bugle. I have yet to find evidence that Kanstul ever made an F marching alto version of the early pattern KAB-175 G alto bugle, or that any other maker made a smaller-bell version of their mellophone. It could be the only purpose-built marching alto ever made.
Nirschl E-102 mellophone: This horn wasn’t intended to be an actual marching alto, it was just Nirschl’s poor attempt at making a marching mellophone. It also works no better as a marching alto as it does as a mellophone…in fact, there is nothing it is good at. But it technically counts?
Andalucia AdVance Series Alto Horn: This is a current-production instrument in F, based on the Kanstul Meehaphone. The Meehaphone was a 2-valve instrument used from 1987-1991, and while it was built around a French horn bugle bell and was essentially a field descant horn in G, it successfully fulfilled the same role as an alto bugle (darker sound than a mellophone, but more projection than a flugelhorn).

As an aside, although they are not really marching altos, there are also bell-front alto horns, aka “solo altos”. These are mostly instruments from turn of the 20th century meant for alto horn soloists and shaped like large cornets. They are usually in E-flat and have much smaller dimensions and a smaller sound, as they are based on concert alto/tenor horns rather than marching mellophones. The Swedish maker Lars Gerdt had a marching tenor horn in E-flat listed on their website until recently.

Anyway, I recently acquired a Kanstul KMA-275 late pattern marching alto in F. It’s the first one I’ve ever seen in the wild; until it popped up for sale locally I had only ever seen the picture of it on Kanstul’s website all the way back in 2002.

The product page for the KMA 275 from Kanstul’s website circa 2002 (via the Wayback Machine).

While I knew the design had radically changed since the early pattern design, I assumed that this instrument would play pretty much like my KAB-175 did, just in F. But it actually plays quite a bit differently. Although it lacks the uniquely sweet sound the KAB-175 had with a tenor horn mouthpiece, the KMA-275 is actually usable with a tenor horn mouthpiece as it plays up to pitch without issue. In fact, the KMA-275 is happy with most mouthpieces you could throw at it.

Rather than describe all of these, here’s a short demo of some of the mouthpieces that work well:

I have to admit, although this instrument is very cool and as well-built and easy to play as you would expect, I would really love to find an early-pattern version of the 275. The KAB-175 was one of the most fun, satisfying instruments I’ve ever played and while this KMA-275 is excellent, it hasn’t made me unwilling to put it down yet. We’ll see if I get there.

Until recently I couldn’t find any existence of the early pattern mellophone/alto design in F at all, and I wondered if Kanstul only started making things other than G bugles after the late-pattern design was introduced. But an early-pattern Kanstul F mellophone recently showed up on eBay (for way too much money, or else I would have bought it already), so the early pattern in F has been proven to exist. But I am still in search of evidence of the smaller-bell 275 F marching alto in the early pattern.

The early pattern Kanstul 280 F marching mellophone from the eBay listing - stenciled as a Besson.

Truthfully, I’d love to get a hold of the complete set: 175 G alto bugle, 275 F marching alto, 180 G mellophone bugle, and 280 F marching mellophone - all in both early and late patterns. Add the King K-50, King 1120, and King 1121 for the complete lineage and I can then determine once and for all which ones are the best.

The mellophonium is the primary ancestor of the modern marching mellophone. It is a traditional circular mellophone with the bell straightened out, and usually has a cornet shank. Even many brass players don’t know what a mellophonium is, and those that do (mostly Stan Kenton fans and alto brass nerds like myself) can be forgiven for thinking that “mellophonium” = Conn 16E. In fact, while the Conn 16E is by far the most famous model of mellophonium thanks to its use in the Stan Kenton Orchestra from 1960 to 1963, it is not the only one. There were lots of mellophoniums (mellophonia?) at the time: Holton M-601 and M-602, Reynolds ML-12, Courtois, Couesnon, Vox Ampliphonic, Glier (in E-flat), and more. You can even still buy a new mellophonium in 2022, courtesy of Amati Kraslice and their 16E-like AMP-203.

My 1969 Conn 16E mellophonium, with Conn 1 mouthpiece

The mellophonium has a cool sound that is related to, but not quite the same as, a mellophone (either the traditional circular or bell-front marching variety). Stan Kenton’s electric 4-man mellophonium section inspired the creation of the mellophone bugle in G for use in competitive drum and bugle corps, which in turn directly led to the modern marching mellophone. The marching mellophone was also the mellophonium’s grave digger, because even the early Olds-pattern marching mellophones were much better instruments.

While not the only kind of mellophonium, the Conn 16E was the first (beginning production in 1957), is the most common to find today, and is the quintessential example of the type. Despite this, it is objectively a terrible design. It was built in F with an E-flat crook, so Conn decided to build the valve slides somewhere in between…too long for F, too short for E-flat! (It actually plays best in tune in E with the main tuning slide all the way out…I’ve played gigs with it that way!) Its intonation is a great struggle, it has extremely wide partials that are tricky to center, it has mediocre long-travel pistons, and it has a whiny and difficult upper register that requires tons of alternate fingerings to get anywhere near in tune. It is also an ergonomic nightmare, and every mellophoniumist has to find a grip that isn’t painful. The “standard” (as much as that word can be applied to anything mellophonium-related) grip is to hold it by the 3rd valve slide, like so:

This is the grip that most of the Kenton section used, although they typically canted the instrument less than I do. Some of them grasped the top of the valve block while others cradled the bottom bow. There are a few ways to do it and it really depends on the individual player, but if you’ve just acquired a 16E and haven’t figured out how to hold it yet I recommend trying my canted 3rd valve slide grip as pictured above.

There is also the issue of mouthpieces. The best mouthpiece for a 16E is unquestionably the Conn 1 that came with it. However, while abused and neglected 16Es can be found easily, the Conn 1 is significantly more difficult to find. If your 16E didn’t come with its Conn 1, the only way to get one is usually to find another 16E for sale that comes with it. The same is true for the E-flat crook, which used to be available through Allied Supply (part # C-06028-5) but is not anymore.

If you are a trumpet or horn player that is used to mouthpieces on the smaller side, the Legends Scodwell Mello mellophonium mouthpiece is a great option. That is a new production mouthpiece from Legends Brass that plays as well as the Conn 1, but is equivalent to a trumpet 5C in size. Too small for many players (including me), but you can likely custom order it in a bigger diameter. The Conn 1 has an inner diameter a touch over 18 mm, the same as a Schilke 22 trumpet mouthpiece.

The third option is a Bach traditional mellophone mouthpiece, which has the right cornet shank for the mellophonium. Before I got my Conn 1 I used a Bach 5 of this type, and it was decent but not great. The low and middle registers are nice and beefy, but the high register is very difficult. The beauty of the Conn 1 is that it works well from the lowest F# (sounding B2) all the way up to the scream register (E above the staff and beyond), while the Bach only works well in the staff and below. The Bach really is much better suited for circular mellophones.

Of course, cornet mouthpieces do fit. But deep British-style cornet mouthpieces don’t do anything well on it, and shallower American-style cornet mouthpieces only work for screamer mellophonium parts. They do hilariously well at that (which is why the Kenton section used them when they wanted to be disruptive), but the mellophonium becomes much more of a weapon than a musical instrument when equipped as such.

So, can the 16E be tamed? Oh yes. The Kenton section had it figured out by the end of its time in 1963, and exceptional players like Ray Starling made it sing (it’s this video that made me want to get a 16E of my own back in 2011). And as someone who has played numerous live gigs and recording sessions on mine, I feel qualified enough to say that I have tamed it. It took years of effort, but I feel that the result was worth it.

Now, the more important question. Should you buy one?

The first thing you should know is that you can get them dirt cheap. They were used in high school and college marching bands for years, and Conn didn’t actually didn’t stop making the 16E until 1979, so there are a lot of them still floating around. As they are completely obsolete, when they get found they are put on eBay and bought for a pittance. The only issue is that you can also get similarly-abused ex-school marching mellophones, including the best-of-the-breed Yamahas, for dirt cheap on eBay. And as much as I love my 16E, my cheap eBay find King 1120, Yamaha YMP-201M, and Yamaha YMP-204M were/are much better instruments.

All that said, I do think neglected 16Es and other mellophoniums (except for the Reynolds, which is apparently even worse than the 16E) deserve to be played and loved, or at the very least turned into cool lamps, rather than left to rot or get scrapped. If you want an unusual brass instrument for your collection, need a dirt cheap alto brass instrument and find a suitably-priced mellophonium, or just think mellophoniums are cool, I would encourage you to head to eBay and pick one up. It’s also an excellent choice for someone interested in multitracking, as it records well and adds a unique sound to any instrumentation. (It also accepts trombone mutes!) If, however, you want a gig-ready dirt cheap alto brass instrument, wait for a good deal on a Yamaha or King marching mellophone.

Just, whatever you do, don’t overpay for one. Nobody should be paying $500+ for a 16E. They are worth $200 at most…maybe $300 in pristine condition with a Conn 1 and E-flat crook. I’ve been noticing 16E prices steadily increasing in the past couple of years and I feel bad for whoever is spending that kind of money on an instrument as problematic as a 16E. I got mine for $100 and I feel like that was the right price.

Now that all that exposition is out of the way, here are a couple of videos I’ve made that make extensive use of my Conn 16E mellophonium in a 4-person section a la Kenton:

Here are some more videos of mine that make use of the 16E in combination with marching mellophones (plus a 5-person Conn 16E soli in the Christmas multitrack):

If you’ve made it this far and want to hear more mellophonium, here’s my work-in-progress attempt at a complete list of albums that include mellophonium. I would assume that all of these were Conn 16Es - the Kenton ones definitely were, and the most recent 4 non-Kenton albums were me on my 16E.

Of course, as mentioned earlier, the Conn 16E was far from the only mellophonium. While it is understandably the one that has seen by far the most use and notoriety thanks to its use in the Kenton band, the other mellophoniums can also be useful instruments. And some of them easily exceed the 16E’s very low bar for playability.

A great example of a refined mellophonium design is the Holton M-602.

The Holton M-602 was the only instrument to be sold as a “marching mellophonium”. Presumably this was to differentiate between the M-601, which had a different wrap. In any case, the M-602 is a much better design than the 16E. It was one of the last mellophonium designs (possibly THE last - mine was made after 1980!), and it shows. It is comfortable to hold, it has slide kickers for the first and third valve (even the renowned Yamaha YMP-204M marching mellophone only has one kicker!), it is easy to play, and it is much more in tune than earlier designs like the 16E. Holton never made a marching mellophone, so it seems that the M-602 was their attempt to compete with the new breed. The result is what I believe to be the only mellophonium that truly feels like a modern instrument. It feels like a cross between the practicality and playability of a marching mellophone, and the sound and feel of a mellophonium.

Now, does that mean it is a replacement for the Conn 16E?

I personally don’t think so. For one, the M-602 is very rare. I’ve only ever seen one turn up for sale online, which is the one I bought. The M-601 is much more common, but it has a much more traditional wrap so it loses a lot of the advantages of the M-602. In terms of ease of acquisition, neither hold a candle to the Conn 16E, which was made in huge numbers and thus grows on trees. But also, the M-602 just does not do the same things the 16E does.

The M-602 has an absolutely gorgeous sound. It is dark, creamy, velvety, chocolatey, and more. Playing it feels like curling up in a warm blanket on a cold winter day. But that exquisite sound does not like to be pushed and it does not like to play high. The Conn 16E invites you to frolic in the upper register and bury a big band, while the M-602 insists that you do nothing of the sort. The M-602 is reserved and polite, and it will not allow you to compromise its elegance. It is an absolute sweetheart, but if you want that Kenton sound you will not get it.

To end this article, here are some pictures of other mellophonium models and prototypes.
