As a Euphonist, I'm concerned that giving trumpets an additional octave will make their egos too large to control. I mean, we can handle that much awesome; just look at our horns. But trumpets? Methinks the village may turn on you, Frankenstein. 🤣👍

For whatever reason I hadn't watched a video from you in a few months and going from a few months ago to now you look absolutely great man. Congratulations on your weight loss.

You've become quite adept at handling Chinesium metal

I did near the same thing 50 years ago when I was in high school. But rather that have the 4th valve as you have made it, I cut the valve tube from a 2nd valve in half and made the 4th valve lower the pitch a quarter step. I wasn't lucky enough to have a torch and soldering skills, so I just glued it together with epoxy cement. It worked great and years later I had a proper repair person solder it up for me. Love the experiments. Good show.

As a low brass player, I have found those 4-valve flugelhorns interesting and have pondered getting one for the possible extended alto range to make up for my lack of high brass chops, lol

Love seeing creative stuff like this. A concern for practicality/necessity often stops a lot of fun from being had. The horn still sounds quite good too!

I’ve been watching this channel on and off for almost 5 years now and was a little shocked to see how you look now. I guess I could say we’ve both lost a good bit of weight since then but congrats!

One of the trumpet players in my brass ensemble plays a four valve flugelhorn. Boy was he surprised when I actually wrote for it. Four valve trumpet..... Better be prepared to use it 😜

I find it amazing how much of a difference you look after losing all that weight, especially after watching a few of your older videos from a few years ago. If it wasn't for your voice, I would swear that you are a completely different person.

I was so ecstatic when I heard a XingBao was being customized.

Excellent Trent, thank you. I recently had an Eb tenor horn customised with a fourth valve - euphonium style for the left hand - and it’s great - nearly four octaves range.

I am in awe. Excellent job making something that plays in tune.

This is very encouraging! I have been thinking of doing something similar with an old 2-valve bugle that I got dirt cheap. It has a wonderful tone and resonance but I'd love to give it a 3rd valve, thereby essentially making it a trumpet in G. That said, I think I might seek a professional's help here in Canada. I don't think I have the skills to do it on my own.

I believe it was Myles Davis who had a four valve trumpet made for him. In his case the 5th valve lowered the pitch quarter-tone. He was experimenting with new sounds. I hope your explorations are good. I'm a tuba player who has a 4-valve instrument which helps in tuning some pitches, and extends the lower range. Some tubas have five or six valves.

Garage mad scientist, are as mad as a hatter, one of the horns looks like the Jean Paul TR430 rose brass lead pipe horn, which was a gift. Strovi, already makes these 4 valve horns, you must know that.....Entertaining vlog.......Tweakers never get tired......

This is so cool Trent! I binge watch your videos all the time. Came up playing trumpet but I switched to tenor sax in college. I still pull out my trumpet and play occasionally though, I keep just enough chops to put brass parts on recordings! You satisfy my inner brass nerd. 🙏

I have been wanting to do something exactly like this! Your videos are fantastic. Great work, and can't wait to see the final product!

Well done @Trent Hamilton can’t wait to see your trumpet some more

This is absolutely incredible!!!

Wow how impressive! you actually made it work!

A really good idea that worked! Time to celebrate!

Looking good my fellow Trent! Hope all is well your way! Keep on keepin' on!

Beautiful sound.

Very nice. Allows to play a few notes in the classical literature that the unmodified instrument has trouble with. Usually low F's (Eb concerts). Now you need a replication of Don Ellis's quarter-tone fourth valve and you've got everything covered.

Pretty Outstanding Well Done!!!

It’s amazing how everything just slides off

Wow this turned out really well! Good stuff!

Looking great!

Interesting content. Superb photography & editing. And an engaging presentation.

Entertaining and informative, as usual. Your self-deprecating humor always elicits a smile. This experiment of yours, suggests to me that brass manufacturers have a market niche they could fill. Reminds me of the four-valve quarter-tone trumpet that Don Ellis used fifty years ago.

Absolutely Amazing!

Stomvi makes a whole range of 4-valve trumpets, cornets, and flugelhorns in every key from Bb up through soprano A cornet/piccolo. They're on the high end of the price range for professional trumpets (though nothing like the like of Monettes) but Stomvi makes great quality instruments.

Wow this is amazing!

Wow, those soldering skillz 🎺

I have never understood why 4 valves on trumpets are not the standard, when literally every other professional brass instrument calls for at least that many.

I love your humor, and your hands are golden. I suggest adding another 8 slides to simulate a one-octave piano keyboard to make the instrument more friendly for pianists too

This is awesome

Great idea. You better patent the improvement before someone steals it.

A+, Trent, very nice job.

wow, you lost so much weight! good job!

Excuse my language, but this video kicked ass. Thank you so much for showing the work and process involved in this. It really came out sounding wonderful. Ya'oughta patent it and get Jin Bao to produce it!

This is amazing

Well done, my favorite musical mad scientist!

2:54 I absolutely love you for this

Havent watched your videos in a looong time, Trent. You're looking great!

Holy cow, that is incredibly cool.

Dude that was so cool! It was so intune, which may have just been the players fault but hey I'm just gonna go with it works. Excellent content.

You are an inspiration Trent. And you have at least 78 thousand friends on here!

Great job!

Cool stuff!

Man you look amazing!

Dude that’s sick

check out a trpt player and band leader from the seventies by the name of Don Ellis. He had a trumpet engineered by Getzen with 4 valves. It was in fact a 1/4 tone trumpet. He also had a very interesting band. Wrote the music for the movie French Connection too!

I want one so bad now!!

Great Video!

"Yeet this away somewhere" amazing

Funny trumpet

An Eb soprano trumpet with a 4th valve to make it a Bb trumpet would be something worth trying.

I did this with 2 Chinese trumpets. One was already a c trumpet so I needed to do a lot more work on 4th valve(and measuring). Worked pretty well but the horns were too cheap to make it any good so it was trashed in the end. I would say for future projects invest in a buff wheel and bench grinder and or just the buff compound itself and use strips of old t shirt to clean up burnt lacquer and unwanted solder and if you want to do it again I say get 2 of the same horn so you don’t have the one valve higher problem. I want to do it again and use 2 olds ambassador trumpets because 1. They’re cheap2. Very good quality for the price3. I can reuse a lot of parts if it doesn’t turn out well

Great, now I want one!! Actually, I've wanted one since I saw the Lotus Trumpet.

I hadn’t watched your videos for half a year, and I am VERY surprised by your looking changed well…!

Wow, that actually sounds good for something that was created by attacking two trumpets with blowtorches, hacksaws, and flat files. I'm not hearing any air leakage. Has a full, rich sound, and for a non-trumpet-player, your trumpet playing sounds pretty good. A lot better than I could do. (I tried playing a trumpet once; sounded like a cross between a cow farting and an eagle screeching.)

That's awesome (I actually said it audibly in my empty den for no one). I really wasn't sure what you were going to come up with, but it wasn't that. Also I didn't expect ot to be in tune.

Lookin good sir 💪🏾👍🏽

I like the use of the word "donor instrument" :D

suggestion: make a french c tuba out of two euphoniums and some tubing

Yo that's pretty cool actually Looks so weird but so cool

I didn't think you would actually pull that off, I might need to try it sometime.

They make 4 Valve Trumpets

Nice one!

Awesome. I've got a tenor horn from the 1890s which is in high pitch, so I have wondered whether as part of a conversion to low pitch, a non-compensating 4th valve would be possible to add. However, this is way out of my skill set and I wouldn't know where to find parts to make this happen.

HEY TRENT HOW ARE YOU THESE DAY'S ! THAT 4 VALVE TRUMPET YOU BUILT IS BEAUTIFUL , I WANT ONE ! A 4 VALVE FLUGABONE WOULD BE NICE ALSO AS WOULD A 4 VALVE FLUGELHORN WOULD BE NICE ALSO !

As a horn player myself I want a trumpet with a trigger it would help it get louder and the high register would be easier to play

Every time I was one of your video I find myself staring at the solo horn on the wall... I want one of those so bad but they're so hard to find

Yes

I'd be happy to trade my social circle for a 4-valve trumpet - what a bargain!

It's amazing what one can accomplish without friends.

Trumpet go peep

Ah yes, the fabled Trentophone

My highschool trumpet mate arron Smith trumpet Smith arron smith made 4 value eb and f trumpets many years ago .

I’m kind of curious, have you ever considered doing a complete showcase of all of your brass instruments?

3:22 "It's gonna be more ergo-dynamic"

I would even buy it

Very nice, but I think you should bend the bell up at a 90° angle so it points upwards like a euphonium (Dizzy Gillespie style).

I want to do that but I know that what will come out the other end will look and sound like an affront to the universe.

What surprised me is that it's the right length for a fourth valve

I was literally just thinking this the other day and what do I stumble upon other than a four valves trumpet

You need to make this a sellable item, I want it super badly.

It sounded pretty good, which surprised me a bit. Would the fourth valve effect the tuning much and with the extra tubing, is it still in the key of Bb?

It would be cool if u could some how get a stomvi four valves trumpet and compare it to yours because they kinda of look similar.

The excellent trumpeter Ibrahim Maalouf has a four-valve trumpet that he uses to play the quarter tones used in arabic scales.

Oh, hitting that low concert-Eb on a descending major arpeggio must feel nice! Always bugged me that the standard trumpets can't hit that note, given how prominent the key of concert-F is on a standard trumpet!

Ya know what, I'd buy one

Here you say that your main instrument is the Euphonium. I always thought it was the trombone. But then, you can have more than one main instrument after all.

Nice! Would you do it with a flugelhorn?

You play Euphonium as your main instrument? Me too! I’ve always thought you played Trombone as your main.

Darn it, I want one

How did you get the 4th value to work that’s amazing

Don Ellis would be proud. Although the extension is not for microtones
