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!
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!
The integrated clamp at the backside of QuantiForce Brass lets you quickly and easily mount the sensor onto your brass instrument. No matter if it is a Trumpet, Euphonium, Tuba, French horn, or Trombone. Feel free to ask for other brass instruments.
Cork padding protects for your lead pipe and mouthpiece from becoming marred.
Connect QuantiForce Brass via Bluetooth to the free companion iOS app (Android Beta available) for immediate display of the measured data while you are playing. Gather helpful insights during play or record the data for offline analysis with your teacher.
QuantiForce Brass was developed in collaboration with Prof. Matthias Bertsch from the University of Music and Performing Arts in Vienna. Watch the videos for his comments on how QuantiForce Brass can help to play safer and to enhance learning (German, with English subtitles):

“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!!
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.
We use biodegradable material from renewable resources (PLA) wherever possible. The electronics are RoHS compliant and produced in Europe.
Measure the force that is applied to the mouthpiece with a resolution of approximately 1 N (~100 gram).
Measure loudness at the smartphone or tablet that runs the app.
Easily mount the sensor and the force plate onto instruments using the integrated clamp without the need of any tools.
See the current lip force and loudness in real-time on a clear display with circle and bar visual elements in the app.
See the relation of lip force and loudness in real-time on a 2D graph display in the app.
See how lip force and loudness vary over time on time series graph displays in the app.
Optionally display the live camera image from the front or back camera of the device that runs the app.
Record the live display to a movie file which you can analyze later or share. Everything the app displays is recorded, including the live camera image if selected.
