If I remember correctly from the physics of musical instruments course I took in undergrad, the cylindrical bore closed-open configuration limits the harmonic content above the fundamental to the odd numbers partials only. A conical bore does not. (It has to do with nodes/anti node locations in the pressure wave at the closed end) this is why a saxophone and a clarinet sound so different. And I believe this is why your clarinet is a more convincing approximation than the trumpet.

Trumpet player here. Your simulation is uncanny. The tension in the lips being higher reduces air volume required and increases air Velocity. The resonance of the horn provides orders of magnitude more amplification than you would expect. The density of the metal plays a role too. Lots of sympathetic resonance in real instruments. Simulation inception would be necessary to capture all of these effects. The fluid simulation is but one part of it. It's probably the most important though which is why your results are so close. Love it man. You should share this tech with music companies like Roland, Yamaha, Nord, etc. They could really benefit from your achievement, and their effects and signal manipulation, user control, and expression technology could make this sound 100% better.

Valve horn player here. Great job on trying to capture this complex procedure! Couple things I know from playing a brass instrument: - The most important part is the lips that distincts between a good player and beginner. I can make my instrument sound like your simulation, just by adjusting my lips. - Air Pressure and Lipstiffness increases with higher notes. Playing loud and deep is as hard as playing quiet and high. But one can compensate this by having a more accurate and more stiff/loose lip - The way I let my instrument sound different with the same pitch is by increasing or decreasing the volume of my mouth. Bigger Volume results in a more round tone that is often nice to hear. But sometimes in certain musical genres you want this duck like quacking and therefore you decrease this volume (by adjusting the tounge mostly). This also is dependent on the tone - higher tones are generally played with less volume while lower tones require more volume for the same quality of sound. Do with that information what you will, just some insights from my end.

I'm a trumpet player too, and loved that this video is a defiantly on point for how a trumpet produces sound. I think some of the parameters that are missing to be able to enhance the sound go something like this..... 1. lips, tension. There's several ways to achieve this, basically we tighten up the cheek muscles to make the lips more tense. In addition, we can change the pressure of the mouthpiece on the lips to achieve the same. 2. Instrument construction. The tone is effected by the mixtures of metals that make up the instrument. I'm talking about he zinc/copper ratio on the brass, which effects the "brightness" of the sound, also whether the instrument is silver plated, or lacquered. Again this finish can have an effect on the tone. 3. And here's a whole new can of worms, what's happening behind the lips. The tongue is important as it's placement will dramatically change the sound, as well how we open our airways in the throat whilst playing. Puffing out the cheeks. Also whether we are breathing with the upper part of our lungs or (as is better) the lower part using our diaphragm to apply the pressure that creates the volume. I believe that we tend to use higher pressure than you'd think to produce the vibration at the lips, but the opening is very small, so that volume of air passing is relatively low. It's common for a trumpet player to be able to sustain a note for about 60 seconds with one breath. This should be able to give you the idea of the amount of air that can be delivered with normal lung capacity.

But I can say that I've heard these kinds of tones from the beginning trumpet player.

To me, it sounds exactly like a trumpet playing into a cushion, or a really closed mute. I think simulating the bell flare will definitely help (I've experienced many dented flares). For even better tuning, the third valve tube would need to be extended slightly in the lower harmonics.
@IONYVDFC11 ай бұрын
I've been a trumpet player for about 10 years, and indeed, the lip parameters are extremely important to hit the right tone. Trumpet players even anticipate their lip setting and sometimes also pull the instrument tighter to their lips to prepare for the next note, at least to minimise the air gap between each note. If not well prepared, it even occurs to players that only air comes out, completely missing the note. As found in the simulation, the amount of pressure lips have endure on a Trumpet is immense, professional players need multiple years of lip training and lip hardening to cover an acceptable tone range. It happened to me to have shattered lips close to bleeding after a concert. The simulation exactly sounds like someone with no experience in lip setting, which is the case here. Lip tension is even changing along the duration of the note, call it expressions, phrasing of the notes or modulation, like vibrato, staccato, pitch bend and more... Adding randomness in lip tension is an easy way to improve realism, but simulating expression with lip tention needs musical feeling, which is a learning process that probably only AI would be able to implement.

Came here to say something similar about the lips. The tweaking of the params to get the 'clarinet' sound definitely made that pop out. I Imagine more work on the flare will help, didn't hear any talk about the "material", i.e. certainly a wooden trumpet would sound much different than a brass one--I don't know how that's accounted for here... maybe covered in a different video, but yeah, so much is in the lips and I wonder if the original model is just inadequate for the needs here. Buzzing with even just your lips, you can quickly start to understand how much that contributes to the sound. I imagine he could also simplify things and just focus on perfecting buzzing with just a mouthpiece and then plug in the rest of the horn to a massive improvement. Hope he decides to take at least one trumpet lesson as I feel like that will be an epiphany on how important that part is.

Incredibly fascinating demo and also a very clear visualization of what exactly is going on physically in a wind instrument and why! I think one of the hardest things about the learning curve of a wind instrument in general is understanding and controlling all those various parameters in real time while only being able to abstractly grasp what the physics behind the instrument actually are doing, so this is amazing to see! Also I definitely laughed out loud when you started playing the Jurassic Park theme haha

Trumpet player here, been playing for about 13 years and just finished my degree in games development. WOW!! Christmas has come early! I find it super interesting that despite modelling it off a real Bb 'key' trumpet (i.e, when you play a 'C', it sounds like a 'concert pitch' Bb), it sounds like it's tuned to Ab. It was a super minor section in the demo, but when you demonstrated the crescendo (going from low volume to high volume), I was blown away by how it accurately simulates the sound 'opening up' - something that trumpet manufacturers can play with to change the character of each instrument. This is awesome!

Oh my god, this is an amazing project. As a passive fluis sim enthusiast, you have just reignited my passion for this field thank you! 1 tip, i think 1 of the reasons why you needed so much pressure to make a noise is the mouth piece. Not sure if the modeled mouthpiece is the same as the simulated one, but the concave section is too small. From what I remember from playing a trumpet in middle school is that the domed section in the mouthpiece was much deeper, and the walls where thinner. Hope that makes sense haha, can't wait to see the next update of this!

Brasswind player, mechanic, and "armchair engineer" here. A huge thing about trumpet playing is that the lips form a seal on the mouthpiece. I couldn't tell if what was shown is what was being simulated, but it appears the lip model wasn't fully pressed against the mouthpiece. This would make a lot of sense why it required so much more air to create a sound, as much of the air pressure can escape around the sides. Playing trumpet well includes having a lot of air pressure behind the lips, as well as carefully measuring out the correct frequency for the lips to move to match the note. Air pressure is achieved by tightening the diaphragm to force the air out as hard as possible. Face muscles control the tightness of the lips. The process of playing is an intricate dance of maintaining air pressure, matching lip frequency to the desired note, and using the correct valves. Also, the bowl inside the mouthpiece affects tone as it changes the shape of the lips and how far apart they can move. When the lips have a shorter distance to travel, they can trill faster, creating a higher frequency. Novice trumpet players can reach higher notes by pushing the trumpet into their lips, forcing the lips further into the mouthpiece to make it easier. Skilled trumpet players have developed their facial muscles enough to tighten their lips without having to do this. Ideally, you don't want to strain your neck by putting any more pressure than is necessary. Some trumpet players make vibrato by repeatedly pressing the instrument into their lips to vary the tone and pitch at the same time. Also, different mouthpieces have deeper or shallower bowls to make it either have a more "full" sound or easier to play higher. Hope this helps. I've enjoyed your engine sim adventure since the beginning. Seeing you make something from it that touches upon more than one of my interests makes me very happy.

As a trumpet player, and a CSE student in a computer graphics class, this is amazing! Idk if it would help, but if an IRL trumpet student is overblowing, it often means they have to tighten up their lips a little. When you have air blown way too hard in the simulation, you can hear the pitch change as the pressure changes the forces on the lips. As a trumpet player, my best sound is made by balancing the tension in my lips with the air pressure. A way to measure if you hit a reasonable balance is to study the amplitude of the sound. When you have a good tension for a given pressure, the horn will resonate better and become louder. This is not necessarily the sound all musicians aim for, but it is a discrete and measurable goal that's good for beginners. I noticed that the simulated trumpet's tuning slides are all pushed in all the way. Pulling out the main tuning slide and the 3rd valve slide (at the same time as the valve is pressed) should improve the overall sound and make the intervals between notes more even. Another thing to consider would be to add tonguing, where the tongue is used as a valve to quickly start each new note. This would eliminate some of the out-of-tune movement of pitch when the valves and slides move. I really love this project you've made! If you have any questions about real trumpets, feel free to hit me up.

You're absolutely correct in describing how a simulation actually does a calculation, but there's a much simpler way of describing it (FEA incoming!). Some terminology: - Node: a single point representing a boundary - Element: a line connecting two nodes together which is represented by a characteristic equation. - Characteristic Equation: the equation that models what we expect to happen based some input (i.e. F = -k•x, ∆Q/∆t = k•A•∆T) Finite Element Analysis is the method by which all simulations solve complex problems that either have dynamic states, or shapes which are hard to represent mathematically. Depending on the problem you want to solve you can either solve a problem in 1D (a line), 2D (a plane), or 3D ( a volume). Typically, most problems are homogeneous (meaning the characteristic equation is the same throughout the entire volume) and we can get away with modeling things in 1D. In such cases, we can break up the problem into some number of nodes (n), and elements connecting the nodes (n-1). Each node has input and output variables and serve as a direct connection between elements, meaning that we can take the reaction from one element to accurately represente the reaction of the following element. An easy way to visualize what this looks like is by thinking about lines at a checkout. When the person at the front of the line is done ordering they move out of the way and the rest of the people in line move forward. Each person represents a node containing the current state, which in this example is position in line from the cashier. What you mentioned about elements only interacting with adjacent elements is a constraint on all FEA models in which we need the output from the characteristic equation to serve as the input for the next element in line. An easier way of thinking of this is by imagining imagining a highway with 4 lanes (2 in each direction). If 2 cars are in 2 separate lanes then they don't interact with each other. However, if 1 car is in the same lane as another car, then said car is limited in how fast it can go by the car in front. Hopefully this explanation helped. FEA is a difficult subject to understand for anyone who isn't in the STEM field, and throwing in fluid mechanics takes the complexity to a whole new level (source: I have my bachelor's in engineering with a focus on heat transfer and fluid mechanics).

Oh my god. Oh my god. This is AWESOME! First of all, this video showed up in my feed while i was in a practice room practicing trumpet. Second, when this is finished, PLEASE PLEASE PLEASE PLEASE PLEASE make a VST3, AU, and AAX plugin for this if you can. Also! As a trumpet player and an audio engineering student I have a few observations, questions, and suggestions which you may or may not have already taken into consideration: It sounds like a french horn, or other low brass instrument. Making it sound more like a trumpet (i.e. generally brighter) is going to come down to the resonation of the metal in the bell. I couldn't tell if you were simulating the actual metal itself resonating, but the temperature, thickness, material, and plating of the metal is going to be very important to the sound. Heres a few parameters that I think could improve the accuracy of the simulation (and are also interesting to tweak): metal materials (i.e brass, copper), plating (gold, silver, none), presence of lacquer, Bore size, Bell size, Bell thickness, Different mouthpieces(??), just to name a few. I noticed that your tuning slide wasn't adjusted at all. Unless it is VERY cold in your room, you are going to need to put it out a little to get proper intonation. Also, when playing middle D (Valves 1&3) the third slide will need to be extended slightly, and fully extended when playing middle C# (123) for proper intonation otherwise they will be very sharp. On the topic of the bore and the bell, these things have a significant effect on the brightness and tone. I play a Bach Stradivarius Model 25L, meaning it has a relatively small bell (brightens the tone and increases projection) and a large bore increases the richness but requires significantly more air. I've played quite a few other trumpets and the difference in intonation and playability is massive. Mouthpiece - not sure if you did research into this. Theres a bunch of different parameters for this (cup size, depth, shape, rim size, thickness, etc.) and it affects both intonation and playability. Each mouthpiece has its pros and cons in terms of range, tone, and playability. You can buy a screamer mouthpiece for playing lead and screech all day long but it wont be very rich and warm. Im not sure if any of that applies tho, as theoretically the simulated lips aren't subject to pain or fatigue. Again, if you aren't already simulating resonating metal id say do that first, as it has an enormous impact on tone. I know thats a lot of things to simulate, but I think it would make a significant improvement. Also, I think the most impressive thing here is what you've done already. It sounds like a brass instrument, and it does tuba pretty convincingly. You just need a few finishing touches (and high end). It would be super cool to see this released to the public, but regardless I'm dropping a sub on patreon right after I finish typing this out so I can start playing around. The ramifications for this in the production community are insane. Hyperrealistic brass instruments right in your daw???? Theoretically, this simulation could be used to recreate room reverbs, without the need for an Impulse Response and convolution reverb. I wonder if there is enough performance optimization available to make a sim that large work effectively in real time. Anyways, this is super awesome, and bravo for making something real that I've only ever dreamed about. I can't wait to see how you improve this, and whatever other projects you have in store.

Trumpet player here, the tone sounded better than most middle schoolers and some on high school. This could be a great interactive teaching tool!

This project is so cool! From what I’ve read about mouth pieces, they actually function as Heimholtz resonators, with another pressure boundary (or whatever its called, like the bell) at the base of the mouthpiece cup. This junction is the interior point at which the vibrating column of air reflects. In real trumpets, the size and taper of the backbore - as well as whatever gap there is between the end of the mouthpiece and the beginning of the leadpipe - has a large effect on tone and slotting (how easily the notes pop out when you play). And the size and shape of the cup also affects whats going on. I know thats a lot of extra stuff to model but would you consider it? Other fun aspects of brass instruments which I’ve wanted to see modeled for a very long time are curvature and bracing. The curves in the pipes of brass instruments seem to function as longer pipes than the straight sections. Brace placement/rigid points along the tube also affects slotting and intonation. I know you’re trying to keep things simple and only doing a straight tube right now but these are some things I would absolutely love to see. Amazing job!

As for the tone, it kinda sounds like you have a mute in. Or like the player has the flu. Newcomers to brass often need to be told to use more air. It actually takes more skill to play well at a low volume. For some reference, back in marching band we measured volume by the amount of time it took to empty your lungs into the horn. Mezzo Forte was "12 count air", as in 12 beats at a given tempo (~120 - 160 ish for marching music). Forte was 8 count. double forte was 4 counts and would rattle the bleachers.

@@Erin-ks4jp I didn't mean as-is, I meant with more work ofc! :D Considering this was made mostly for a fun quick video, and the video mentions many things that need to be fixed to improve it, I think the potential is there though, if it was focused on.

Sounds already great, even with parts missing Just a few questions: Do you handle partial valve opening, not that I know how that sounds on a trumpet? And do you think it's feasible to simulate the resonance characteristics based on the material and shape of the tube, to my knowledge it's a important part of the sound of some instruments, and I guess it could be approximated by estimating the volume change of the tube based on the internal pressure. Anyway keep up the great work, always learning something new watching your videos

Partial valve opening: this is accounted for in a realistic way. If it wasn't accounted for, the transitions between valve released/pressed would sound extremely harsh and synthetic. The simulator does allow you to hold the valve in the middle position if you really want to. Material resonance: "maybe". To some degree it supports this when it comes to sound wave reflection, however, the vibration of the material is not something that I've really looked into in great detail. Thanks for watching!

The sound breaking up at 18:48 is spot on for the state the simulation is in, I had that happen quite a few times when learning a decade ago and to hear a simulator replicate it almost perfectly is amazing
