QuantiForce Brass
QuantiForce Brass
Your Individual Lip Pressure Display
Learn easier
QuantiForce Brass supports you to develop your playing technique and to play and practice more efficiently. Learn how to use just the right force and improve your technique rapidly.
Play safer
Keep an eye on the force applied to the mouthpiece. An appropriate force can be beneficial for the health of your lips and body and can increase your playing endurance. Your lips and your whole body 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!
Install within seconds
Fits virtually any brass instrument
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.
Immediate visual feedback
See the invisible forces
Connect QuantiForce Brass via Bluetooth to the free companion iOS app (Android Beta available on request) 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.

What experts say
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 best thing that has ever been made to control how much pressure you put while playing."
Andrea Tofanelli,
International Trumpet Artist and Clinician
"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.
Environmentally friendly
We use biodegradable material from renewable resources (PLA) wherever possible. The electronics are RoHS compliant and produced in Europe.

QuantiForce Strings
QuantiForce Strings
Revolutionary Tools for Bowed & Stringed Instruments
Efficiently teach ease of play
QuantiForce Strings supports teachers and students in identifying the situations where the player’s body does not have the suitable amount of tension and where the teaching work should focus to efficiently improve the ease of play. On the other hand, as soon as there is an improvement it is immediately visible for teacher and student, which is a big motivating factor for everyone involved!
Reduce health risks
Our studies have shown that some musicians are using significantly more force than others for playing the same phrases. While many stayed in the range of 0.5 - 1.5 kg of force on the shoulder, some were exceeding 10 kg! And there was no noticeable difference in sound, posture, or motion that would indicate the high force. Such high forces come from strong muscular tension and can seriously harm the musician’s health when accumulated over a career.
QuantiForce Strings makes it is easy to identify such risks and the real-time display of forces supports teachers, students, and musicians to evolve to a healthier playing technique.
Enabling new levels of research
For the first time it is now possible to collect very detailed and informative force and motion data of musicians playing in their natural environment instead of a laboratory setting. The QuantiForce Strings sensors unobtrusively integrate with the instrument and are astonishingly easy to set up with our Logger app. There is no need to hire a technician to use the system.
With the Logger app it is simple to combine different sensor systems. For example you can add QuantiMotion full body motion capture to the same recording and/or use the mobile device’s internal camera to document the entire scene on video. The app displays live data of all sensors and you can record and export the data or use our cloud storage to get centralized access to all collected data.
How does it work?
QuantiForce Strings is a completely new set of sensors that are either integrated into the shoulder rest or are available as thin, flexible foils that can be applied to the instrument or bow at the contact point of the fingers or knees. The sensors continously measure the force between musician and instrument at those contact points and motion of the respective parts. Our Logger app for mobile phones and tablets wirelessly connects to the sensors and displays (and records) the relevant forces and motion data in real time.
"Since I've been using QuantiForce, I've finally gotten my years of neck problems under control."
"The convenient visual representation gives me instant feedback of my effort level as I practice."
"My attention to pressure while playing has become so automated that I can instinctively avoid severe muscle tension even during orchestra rehearsals."
"For many years, I thought neck tension was just part of the professional musician's suffering, until I integrated QuantiForce into my daily practice."
Celina, professional violinist Actively used by teachers in music schools
QuantiForce Strings is actively used by music school teachers. Watch the video to find out how Ulf Prelle, solo cellist at Dresden Philharmonic, uses the system in his lessons. (German audio, enable subtitles (CC) for English.)
We offer QuantiForce sensors for all finger forces on stringed instruments and for chin and shoulder forces on violin and viola.
