Learn Easier

QuantiForce Brass supports you in developing your playing technique as well as playing and practicing more efficiently. Learn how to use just the right force and improve your technique rapidly.

Play Safer

Focus on the force applied to the mouthpiece. An appropriate force can be beneficial for the health of your lips which can increase your playing endurance. Your lips will benefit from an improved force awareness.

In Class and At Home

QuantiForce is the ideal companion for teachers to spot problems in class. At home, musicians can record their practice sessions and discuss them later with their teacher.

 

 

 

Get important insights

Protect your lips!

QuantiForce Brass is the ultimate tool to gather objective and individual insights in brass playing. Measure lip pressure at the mouthpiece with unprecedented precision and combine it with sound pressure level measurements that capture even your loudest tone. See all data in real time for an immediate feedback on your playing or record the data for comparison with other players or later analysis.

Raise your playing awareness with ease - at home, in class and even on stage!

 

 

 

Teaching and Learning

A powerful tool for both

With QuantiForce Brass applying the appropriate force is made easy. Both teachers and students have a powerful tool at hand to see the actual lip force while playing, which was never that easy before. Several visualizations help to understand the force applied in different playing situations and in relation to loudness or played notes. And - to make it even more useful - visual alerts can be adjusted individually with your fingertips.

 

 

 

With this supportive tool inappropriate lip pressure is recognized immediately or even avoided in advance. Explore new and exciting ways of teaching and learning with QuantiForce Brass by Bonsai Systems!

Testamonial From Andrea Tofanelli

International Trumpet Artist and Clinician, check out his YouTube channel

“The Bonsai System is probably one of the most important because you can see in real time how much pressure you put in your playing and it’s incredible, this is not only useful for students also for the professional players and for the professors it is incredible.

I’ve been playing the trumpet for 44 years, there have been some things speaking about this problem, you know trying to fix this problem. This is probably – for sure the best thing that has ever been made to control how much pressure you put while playing, so I’m totally for these and what can I say this is useful! This is completely useful!!

"I made big progress in range and really, really big progress in endurance."

Jakob, trumpet student,

after 10 months of using QuantiForce Brass


We gave QuantiForce Brass to Jakob who is studying trumpet. Since then, he is using QuantiForce Brass in his daily practicing. In the video he talks about his experience with QuantiForce Brass and how QuantiForce Brass has helped him to reach his learning goals.
