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.

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.

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

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 😜

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......

Actually, if the video was unpublished, we WOULDN'T have known the project was an abject failure!

They make 4 Valve Trumpets

Love seeing creative stuff like this. A concern for practicality/necessity often stops a lot of fun from being had.

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!

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.

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.

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. 🙏
