I'll admit: just before you started playing, I had a moment of anxiety at the thought that any of the weird designs might actually be a drastic improvement, and we would all have to change all our mouthpieces.... Bullet dodged.

Being a low brass player, I would love to see a similar experiment with trombone or euphonium mouthpieces.

That deep cup makes it sound like a cheap euphonium.

What would happen when you put a deep mouth piece into a already mellow instrument? Would it cause mass depression due to shear sadness you could make? Maybe. But would it be interesting. Probably not to most people. BUT WE ARE NOT MOST PEOPLE

The square sounded pretty nice imo, gave the horn a nicer, mellower tone.

Something like the off center one might actually help in marching bands to help with horn angles for trumpet and baritone.

What if you have the mouthpiece as normal, except that it expands again after the cup, kindof a \/ /\ | | \/ | shape

I feel like with the deep mouthpiece, the trumpet solo in “go down gambling” by blood, sweat, and tears would sound AMAZING

Will your mellophone accept that deep mouthpiece? I bet that would sound a little interesting =P

3d print a tuba mouthpiece with a trumpet shank, bass trombone with trumpet mouthpiece but the opposite

You should try taking mouthpiece designs from other brass (like a horn or tuba) and scale them up/down until they fit in a trumpet.

Trent - brave attempt, and the square sounds actually surprisingly close to useable - I was expecting them all to have significant issues, but that wasn't too bad at all. The challenge with mouthpiece design (or modifications, which in many ways are the easiest way of getting to grips with how the different elements interact) is that different parts of the mouthpiece need to balance out with others... It all basically comes down to intonation patterns - bad mouthpieces will generally either compress the octaves (flat up high and sharp down low) or they'll expand them (sharp up high, flat down low). This is basically what's wrong with your "very deep" model - it sounds compressed, you could try shortening the length of the backbore... in short - cut off a couple of mm from the end of the shank, then sand down the outside of the shank to restore correct insertion (the diameter at the very tip ought to be measuring somewhere similar to your Bach mouthpiece anyway, right?)

Can you please do a review of a cheap C trumpet. I'm looking for one and I would love your help!

What about a tuba mouthpiece with a bore size small enough to fit in a trumpet leadpipe

Is it just me or does the really deep mouthpiece kind of sound like a saxophone at some points?

First I thought that you have too much time on your hands. Then I thought that being able to tweak cup depth or rim size, etc. could be a revolutionary to design a mouthpiece to suit me individually.

Keep experimenting! This is so cool!

I would say try the one that's deep on a bigger instrument like a baritone

The square mouthpiece is used to blow square notes

I feel like someone could do some very interesting stuff with that extremely deep mouthpiece. Perhaps something jazzy? Not sure.

Keep doing this my friend ! Great job! Congrats from Brazil

I 3d printed a trombone to french horn mouthpeice adapter for my son who plays "the horn". The adapter also corrects for what I consider a design defect of french horn, that is requiring you to stick your hand in the bell to not play sharp.

the square sounds good!

you can do a deep V cup to get a nicer sound and less tuning problems, as long as it's not that deep. but like a Bach 5V. I've also designed a mouthpiece based on a shilke 28 horn mouthpiece that's been extended to but my Con 16E mellophonium back in the key of F (mine was in F#)

This is great! Could you please do more videos like this?

print out a billet trumpet that externally is a solid rectangular block ! (no external tubes)

I can see a music store instead of stocking a lot of expensive mouthpieces keeping a library of cad files and being able to supply whatever a customer wants. Probably comparable prices and profit.

Trent, I currently use a 1G Bach mouthpiece in my bass trombone. I like it because it has such a large deep cup size. A friend gave me a tuba mouthpiece to try, one he'd turned down the shank in the lathe to fit smaller size (eg large bore trombone). The sound was very dead compared to a normal trombone mouthpiece. The "very deep cup" you tried in this video sounded to me to be (almost) muted. Given the problems of register etc, I wonder if you made it just not quite so deep if it would sound better and/or be easier to blow. So putting the two concepts together; I think the tuba mouthpiece was too heavy and too big (diameter) for the trombone. However, I wonder if one was made to bass trombone diameter but as deep or slightly deeper than a tuba mouthpiece, what would it be like for sound and for playing. Now, on the other mouthpieces: Square; did you try playing it turned 45 degrees (so that it "faced" you as diamond shaped). The Offset; sometimes, especially on a tuba, there is need for a "bent" leadpipe to bring the mouthpiece further around the bell for playing. But how about if the mouthpiece was already "bent" rather than just offset?

Sweet sound

The deep one gives it a weird jazzy feel Like If you tried playing blues on it, it would sound great

I did not expect to hear Spain without asking for it thank you

The deep cup sounds jazzy and I like it. Can you give me the cad file? My local mall has a 3D print shop last I checked

You know what would be fun? It's a trumpet that uses a bigger mouthpiece but still fits in the horn. Like sticking a trombone mouthpiece into it but it works and it's not like terrible

The extremely deep-rimmed mouthpiece makes the trumpet sounding like a mute cornett...

With the offcentre one. Doesn't it mess with the up/down stream of the embouchure? Try some standard lip exercises with it.

what about the double trumpet mouthpiece you teased us with?

Trent have you been practicing your trumpet chops? 3d printed mouthpiece or not, you sound great! I can tell you've been hitting the shed

The big cup reminds me of a megatone mouthpiece at first glance. Granted, I don't know what megatone is supposed to accomplish, I've only seen them be used in a school setting by someone who wanted to play really low and really loud. With the mellow tone from the 3D print, with some design improvements it could be interesting for someone playing a 3rd part or try plugging it into a flugelhorn.

Perhaps make a mold of your embouchure and design a mouthpiece to fit it? Or even easier, grind out an existing mouthpiece gradually to fit it. You can fill it back with epoxy glue.

The deep one kind of reminds me of playing a trumpet with a French horn mouthpiece.

I dont know about trumpet mouthpiece's but on the tuba the deeper the cup the more air/preasure you have to add, but it helps tubas get another low range octive

How much smoothing have you done on the mouthpieces? Sanding/acetone smoothing? I could see a use for specialty mouthpieces e.g. if you’ve got a tooth damage. Or might an oval mouthpiece be more comfortable for long concerts? Maybe shape the rim but keep the inner dimensions?

The deep mouthpiece makes the high register sound bad, but the low register sounds really nice, kind of flugelhorn/french horn like.

This reminds me of something I saw about 40 years ago. It was a set of mouthpieces called 'The Doublers Mouthpiece'. In the box were 'French horn', 'trombone', and 'tuba' mouthpieces. Each was basically the shape and depth you'd expect, but the rims were all identical and the size of a trumpet mouthpiece. So the 'Tuba' mp was close to your 'very, very deep' mp... actually it was probably deeper. As a young know-it-all man I thought it was stupid and passed on purchase. I should have bought them. At worst, a collectors item.

You should try to make a less extreme deep mouthpiece, giving a little more ease of use but still a comparable shift in tone

Wick actually makes (French) horn mouthpieces like that second one. They look like a Bach Megatone, but the cup actually IS that deep. They're not my favorite.

How about making it wider as well as deeper? I own a Schenke 24 mouthpiece--I;m told it's one of the largest out there--for my alto trumpet.

Hey Trent, Great idea. Could you share with us the hardware/software you are using to design and print these mouthpieces??

The other variable with the too deep mpc is lower mass. How about wrapping it with lead wire to increase the mass ?

The piece you played to test these: Herbert L. Clarke? Very interesting vid; thanks.

Did you try the square mouthpiece with the top and bottom parallel to your teeth line or did you try it with the teeth line going through the corners of the mouthpiece (as if playing a diamond)?

Hi there Trent, could you try the deep cup mouthpiece with a flugelhorn or a cornet ? Yes you may need to reprint another one because of the backbore size. Oh well you already know that. Chur Bro !!

you should try selling the deep cut mouthpiece. it has such a unique sound, it's almost saxophone like or euphonium like. i know i would buy it myself. also you should try making an asymmetric mouthpiece

Interesting video!

Can you test a deeper mouthpiece, like this one, on a flugelhorn?

try the cup mouthpiece in a flugelhorn, see if that makes a difference

The deeper mouthpiece kinda sounds like the trumpet has a mute in it? Also, I know you won’t see this but would you be willing to do something lime this but with a baritone/trombone size?

The second one is for those who want to know how they will sound once they get old. I mean it's literally for when you're in the bottom of the well

That deep-cup mouthpiece almost makes it sound muted by a harmon w/o stem

Try a mouthpiece with an interior spiral or cyclone which may increase the flow rate.

What program did you use to design those mouthpieces? I’ve thought about doing some experiments myself.

The square mouthpiece produces square waves

I printed a trombone mouthpiece that fit in a French horn and it is very good

I am wondering if a deeper NORMAL Mouthpiece would allow for a more air ish sounding tone? the "deep mouthpiece" seems to provide a bit of this. could you explain how that tone is achieved?

It sounds like it would be good for jazz

If it were made out of brass I think it would be better and in my opinion it makes it sound naturally jazzy

I could see the Deep Mouthpiece Being Redesigned into a Real mouthpiece because of its mellow Sound

I wonder what would happpen if the 3D prints were used to make molds and cast mouthpiece's from diffrent metals like, brass, copper or steel?

You might have a word with your designer on the Spreadshirt merch. The Tuba takes up a reasonable span of space on the various printed items, but the Trumpet and Trombone seem to disappear into the background because they're so small.

I would like to see something similar to the Wycliffe Gordon mouthpiece for trombone-to-trumpet...

The offset one reminds me of a toilet . . . i want one!

I’m attempting bluebells for competition as a freshman. Any advice/suggestions?

my boi playin aranjeuz

Have you tried the deep cup on a mellophone yet? I feel like it would fit a bit better for the instrument, even though it’s still ridiculously deep

Orange juice sounded almost exactly like a flugel when you started out, before it got higher.

Bro his tone is so full and bright

I can’t help but feel that the deep cup mouthpiece would work better on a Mellophone or a flugelhorn

What was the first example you played with only the deep cup mouthpiece called?

I was hoping one would have a bulbous bubble below the rim, a bit like the profile of a thistle. :-)

I know that solo from some where i just cant remember it.

I feel like you could alter the deep one to make it more ridiculous. Maybe make it so deep that the cup stops at the receptor

spain is such a cool piece

Use the deep cup on a flugle horn or mellophone

Perhaps it’s time for the flatulence powered 3-d printed .. what shall we call it.. derrière piece? Of course the required tubing would flatten the instrument tremendously requiring you to hammer the tunning slides in well past the limits.

Is there a place I can find that 3rd mouthpiece file? I want to print one as a gag

How about a trumpet-style mouthpiece that will fit the Frumpet?

I like the deep one!!!! It's weird! Maybe not that deep could work better

What if you made a deep mouthpiece so deep that it would flatten the tone with a complete semitone? Then you would (kind of) have no tuning issues anymore.

I would have to say none of these are "a roaring sucess"😂

Was that Concierto De Aranjuez I heard?

Hey, do you have the files for the deeper mouthpiece?

The deep mouthpiece makes the trumpet sound like a French horn.

I once tried a Conn Liberati cornet mouthpiece. It was nearly as deep as your absurdity. But it was also the most comfortable and flexible one I ever played. Anyone out there with a 3D printer who needs a project?

what about the double-shanked mouthpiece You showed in a text post?

Wow super awesome video! I have a 3D printer and LOVE stuff like this. Any chance you might possibly release the files on Thingiverse or similar for us to print and try out ourselves? Thanks!

Could anyone leave he name of the origin for the excerpt Trent used for the mouthpiece tests?

Hi Trent! I was wondering if you could print a trumpet mouthpiece that is in the shape of a french horn mouthpiece? I want to see if it would work, as I love the sound I get with I use my french horn mouthpiece with my trumpet

A corkscrew bore after the cup?

Any plans to share the CAD files?

Make a mouthpiece that is almost like a cra-z straw or one that is at a ninety degree angle almost like a saxophone
