Does a carbon fiber trumpet take less energy than brass?

Yes. A daCarbo takes about 10 percent less energy for the same result, measured in the lab, in Vienna in 2012. Here is how that came about, what it changes when you play, and what it does not.

Published · Updated

Third set. Half past eleven, maybe later. You have been on stage since eight. Your lips are numb, your air is running thin, and the high C is still to come.

Anyone who plays long gigs knows this moment. The band wants one more tune. Your chops want to go home.

Almost everyone looks for the reason in themselves. Practise more, pace yourself better, try another mouthpiece. Hardly anyone asks how much of it comes from the horn.

Is it your chops or your trumpet?

Both. Your embouchure is something you build over years. On the instrument, one thing can change: how much of your energy gets lost in the bell.

No horn makes you a better player. It changes what a note costs you. That is exactly the question a trumpet player asked himself, who also happened to be a materials scientist.

How did a materials scientist end up making carbon trumpets?

Andi Keller, the founder of daCarbo, studied composite materials and spent seven years in research. After that he ran a development department that made loud machines quieter. The principle: composites damp vibrations.

Andi has played the trumpet since he was a child. So the question was close at hand: what happens if you apply the same principle to a trumpet?

He could not make an instrument himself. For a year he told his idea to anyone who would listen. Then he met Werner Spiri, one of the best-known wind instrument makers in Switzerland. After ten minutes Spiri said: let's do it. Two weeks later the two of them founded the company. daCarbo has made carbon wind instruments since 2009.

What did the Vienna institute measure?

With the first finished prototype, daCarbo went to Vienna, to the Institute for Musical Acoustics (Wiener Klangstil) at the University of Music and Performing Arts Vienna. Acousticians there have studied wind instruments for decades.

The acousticians Vereecke and Kausel compared the same trumpet once with a brass bell and once with a carbon bell. They measured how much energy the instrument needs for the same result. In 2012 the study appeared in the International Trumpet Guild Journal, the journal of the International Trumpet Guild.

How much energy does a carbon trumpet save?

About 10 percent less energy for the same result. Measured in the lab. That is the one number that is proven. Not a feeling, not a line from a brochure, but a measurement from Vienna.

10 percent sounds small. Until you play a night with three sets. Then it is the difference between a last tune you play through and one you only survive.

You have more left at the end of the night.

Why does a carbon bell take less energy?

Where a brass bell vibrates and loses energy, the carbon bell stays still.

Every vibration in the metal takes energy. That energy comes from your air and your lips, note after note, all night. The carbon bell is made so that the material itself hardly vibrates. What you put in goes into the note.

It was not simple. daCarbo first compared straight tubes made of glass fibre, carbon and brass. Carbon came closest to brass acoustically. Then came prototypes with different wall thicknesses and fibre directions, play tests with musicians and changes to the metal parts. The goal never changed: a trumpet that sounds like a trumpet and plays like a trumpet. Only with less effort.

What does a carbon trumpet feel like to play?

The note speaks faster. Andi describes it like this: you can start a little off the centre of the note, and there is still enough energy for the note to come. That builds trust. And a player who trusts the instrument plays more relaxed.

Many players do not notice it on day one. The independent reviewer TrumpetScout felt nothing special at first. After a few days, soft entries and high notes spoke more surely for him. So give it more than one evening.

Does a carbon trumpet sound different from brass?

No. Nobody hears the difference. In a blind test, listeners could not tell carbon from brass.

That was on purpose. A carbon trumpet that sounded different would have no place in an orchestra or a big band. What changes, you feel in your hands, not in the hall: the bell gives less feedback, because it does not vibrate.

Is a carbon trumpet lighter?

No, and that is not the point. Carbon, not because it is lighter. Because the bell stays still, warms up in seconds and does not dent or corrode.

daCarbo even had to add weight, for acoustic reasons. A Unica weighs about 1.03 kilograms, about as much as a brass trumpet. If low weight is what you need most, a daCarbo is not made for that.

Carbon or brass: the comparison

Brass trumpetdaCarbo with carbon bell
SoundThe sound you knowThe same. Listeners could not tell them apart in a blind test
EnergyThe bell vibratesAbout 10 percent less, measured in the lab
WeightAbout 1 kilogram, depending on the modelUnica about 1.03 kilograms
Dents and corrosionThe bell can dent and corrodeNo dents, no corrosion on the bell. The metal parts like on any trumpet
Warming upThe metal takes timeWarm in seconds

And does it last? Five times stronger than it needs to be. None has broken since 2009.

Who is a carbon trumpet for?

A daCarbo makes sense when endurance is your issue:

  • You play long gigs. Big band, dance band, festivals, weddings, three sets a night. Your chops give out before the band does.
  • You are coming back after a break. Your endurance is not what it used to be, and you do not want to fight for every note.
  • You play lead or first part. High register, lots of entries, no room for mistakes.

A daCarbo is the wrong choice if low weight is what you want most, or a new sound. The sound stays the same.

Which daCarbo trumpet is right for you?

There are four trumpets, from bright to full. All of them have a carbon bell.

  • ChangeMaker, from €2,990. The way in, bright. The most affordable way into a carbon instrument.
  • Unica, from €3,990. The all-rounder, brilliant and balanced. If you only try one daCarbo, try this one.
  • Toni Maier, from €6,590. Warm and open.
  • Large, from €7,990. Full and very open.

The price includes tax, customs duty and shipping. Nothing is added when it arrives. Handmade in Switzerland. Andi assembles and tests every instrument in Lachen.

Can I try a daCarbo before I buy?

Yes, in two ways. First: 30 days to send it back from the day it arrives. Second: a call with Andi before you order.

The call takes 30 minutes on video. Andi hears how you play first. Then your instrument is chosen. If no daCarbo suits you, he tells you straight. The call costs nothing and commits you to nothing.

Back to the third set

Half past eleven. The band counts in the last tune. You are not working less hard than the others. You just lose less on the way, about 10 percent, measured at the institute in Vienna.

You have more left at the end of the night.

Common questions.

Does a carbon fiber trumpet take less energy than a brass trumpet?

Yes. About 10 percent less energy for the same result. Measured in the lab, at the Institute for Musical Acoustics (Wiener Klangstil) of the University of Music and Performing Arts Vienna (Vereecke and Kausel, International Trumpet Guild Journal, 2012).

Why does a carbon bell take less energy?

Where a brass bell vibrates and loses energy, the carbon bell stays still. Every vibration in the metal costs energy from your air and your lips. The carbon bell hardly vibrates, so more of it goes into the note.

What is the most energy-efficient trumpet?

No standard test ranks trumpets by energy, and your own playing matters most. What has been measured: the same trumpet needed about 10 percent less energy for the same result with a carbon bell than with a brass bell, in the lab (Vereecke & Kausel, International Trumpet Guild Journal, 2012). That is why daCarbo makes its trumpet bells from carbon.

Does a carbon fiber trumpet sound different from a brass trumpet?

Not to a listener. Nobody hears the difference. In a blind test, listeners could not tell carbon from brass. The player feels a difference in the hands: the bell gives less feedback, because it does not vibrate.

Are carbon fiber trumpets lighter than brass trumpets?

No. Carbon, not because it is lighter. Because the bell stays still, warms up in seconds and does not dent or corrode. A daCarbo Unica weighs about 1.03 kilograms.

Will I feel the difference the first time I play it?

Maybe not right away. The independent reviewer TrumpetScout felt nothing special on day one. After a few days, soft entries and high notes spoke more surely.

Who is a carbon fiber trumpet for?

For players whose issue is endurance: long gigs with several sets, players coming back after a break, lead players. You have more left at the end of the night. If you mainly want low weight or a new sound, a daCarbo is not the right choice.

How much does a daCarbo carbon trumpet cost?

ChangeMaker from €2,990, Unica from €3,990, Toni Maier from €6,590, Large from €7,990. The price includes tax, customs duty and shipping. Nothing is added when it arrives.

Do carbon fiber trumpets break?

Five times stronger than it needs to be. None has broken since 2009. The carbon bell does not dent or corrode.

Can I try a daCarbo before I buy?

30 days to send it back from the day it arrives. Before that, a free video call with Andi Keller: Andi hears how you play first. Then your instrument is chosen.

Does the 10 percent energy saving apply to carbon fiber trombones too?

Not proven. The study was about trumpets. daCarbo makes carbon trombones too, but we give no number there without a measurement.

Who makes daCarbo carbon trumpets?

daCarbo AG in Lachen, Switzerland, founded by Andi Keller and the instrument maker Werner Spiri. Handmade in Switzerland. Andi assembles and tests every instrument in Lachen.
