Why CarolBrass Developed – The TriKeyPro





Why CarolBrass Developed a Brand-New Concept Trumpet – The TriKeyPro
At CarolBrass, we've had the privilege of running our tourist factory for over nine years. During this time, we've encountered countless visitors—many of whom come specifically to see or inquire about saxophones. This shows that a lot of people are deeply fascinated by the idea of playing the saxophone. However, we’ve also noticed that many visitors don’t clearly understand the difference between brass and woodwind instruments. We're glad to have this opportunity to share some insights.

At first, we assumed that these saxophone enthusiasts had never tried the trumpet before. But surprisingly, many of them had learned trumpet before switching to saxophone. This naturally raised the question: why didn’t they continue with trumpet?

This question often came up during our tours. As conversations unfolded, we’d learn that the guests were sax players. And when we tried to introduce them to the trumpet, we could sense some hesitation. It was as if there were unspoken challenges or frustrations associated with the trumpet.

One of our long-time manufacturing partners, who frequently follows our Facebook activities, once told us that he and his wife were planning to take up the saxophone after retirement. Curious, we asked why they didn’t consider the trumpet instead. His response was honest and revealing:

“From what I’ve seen, trumpet playing looks like it requires a lot of effort. I’m worried I don’t have the lung capacity. Plus, those high notes sound not just loud, but kind of painful. It’s intimidating.”




A Visual Explanation: Why the TriKeyPro Was Born
1. Traditional Bb Trumpets – Easy at First, But Challenging Beyond a Point
(Refer to the red circles in the diagram above)
The lowest notes on a Bb trumpet—Low G (So), A (La), B (Si), and up to high C (Do) — are actually quite easy to learn. With serious practice, most students can learn this range within 1–3 lessons, and no strong air pressure is needed.

However, notes above high C are much harder and require significant endurance and daily practice to maintain. These high notes are essential in orchestras and jazz bands, but when used in modern pop music, they often sound too piercing and out of place. This difficulty discourages many from sticking with the trumpet.





2. Why Saxophones Became Popular in Pop Music
(Refer to the red circles in the diagram)
Saxophones, like Bb Tenors and Eb Altos, naturally sit in a lower range. Their lowest note is usually a B. When transposed up—Tenors by an octave or Altos to F or G—the resulting sound is rich, capable of reaching the low G (So) and A (La) ,warm, and fits perfectly with modern pop songs. These transpositions land in the baritone and alto vocal ranges, which appeal to contemporary tastes. This is why saxophones have exploded in popularity in Taiwan.





3. The Trumpet’s Limitations in Lower Registers
Because of their limited tubing length (~1.4m), Bb trumpets cannot easily access lower keys. When transposed to G, they lose the low G (So); in F, they lose both G and A (So and La). (See red-circled areas.) This makes it hard for trumpet players to play in keys suitable for pop songs, which often rely on these lower notes.

Over the years, our interaction with a wide range of people helped us uncover the real challenge: promoting the trumpet among amateur players in Taiwan has become increasingly difficult.

So, we came up with a new idea: what if we created a system where players only needed to learn one traditional fingering and just 11 key notes (up to high C(Do) in the key of Bb trumpet)? Then, by extending the tubing to lower the pitch (i.e., transposition), players could access the crucial low G and A (So and La) needed for popular songs.

This led us to launch:

A Bb–G trumpet four years ago

A Bb–G–F “Saxy Trumpet” two years ago

And interchangeable G and F slide kits for all CarolBrass trumpets one year ago

“This new design allows players to experience the joy and satisfaction of playing music in a short time, and builds motivation for long-term learning.”

Now, we've taken it one step further: a trumpet that transposes even more easily — the TriKeyPro Trumpet. With a simple design, players can effortlessly switch between F, G, and Bb using a single fingering system.

We hope this new concept trumpet brings new energy to Taiwan’s trumpet community. We hope it reignites the passion in amateur players and opens up new opportunities for skilled trumpet teachers to connect with students and ensembles across the country.

Learning the trumpet should not feel like climbing a mountain of pressure. It can be a personal, joyful journey — where music meets the soul. Start relaxed, fall in love with the sound, and grow in confidence. Let the trumpet’s voice resonate through every corner.

From an easy first step to bold musical heights, the TriKeyPro Trumpet is here to help you embrace the challenge and chase your dream.




Notes:
(See red-circled areas) The high C on a Bb trumpet equals D♯ on a G trumpet and F on an F trumpet — the air pressure required is identical. So, if you can play high C on a Bb trumpet, using longer tubing lets you reach lower keys with ease, making modern pop songs easier to learn than on any other instrument.

We recommend using original key sheet music (not already transposed or filled with accidentals). For songs peaking at high C, use Bb mode; if they go to D or E, use G mode; and if they go to F or G, use F mode. This keeps the character of the song while sparing you the strain of “pushing” high notes — with our method, even long street performances become effortless!

Many pop songs feature crucial low G and A notes. These notes are essential to the feel of the music and should not be overlooked.
