QuantiForce Brass

Your Individual Lip Pressure Display

QuantiForce Brass mounted at the mouthpiece of a trumpet.

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 coming soon) 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.

Live feedback on tablet and smartphone.

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):

Measure the force that is applied to the mouthpiece with a resolution of approximately 1 N (~100 gram).

External Loudness Measurements

Measure loudness at the smartphone or tablet that runs the app.

Toolless Installing

Easily mount the sensor and the force plate onto instruments using the integrated clamp without the need of any tools.

Force & Loudness Display

See the current lip force and loudness in real-time on a clear display with circle and bar visual elements in the app.

Force vs. Loudness Display

See the relation of lip force and loudness in real-time on a 2D graph display in the app.

Time Series Display

See how lip force and loudness vary over time on time series graph displays in the app.

Camera Image Display

Optionally display the live camera image from the front or back camera of the device that runs the app.

Save to Video

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.

Lip Force at High Resolution

Measure the force that is applied to the mouthpiece with high resolution of approximately 0.1 N (~10 gram).

Comparable Loudness Measurements

Loudness measurements depend on the distance to the source. This sensor measures the loudness at a fixed position relative to the instrument in order to receive comparable values.

Quick Detach & Reattach

Easily mount the sensor onto instruments using the bracket. Quickly detach and reattach the sensor while leaving the bracket at the instrument.
