Stopping, known as stopfen, is employed by many Classical and modern composers. Usually, stopping is accomplished with the hand. But this is not always a simple matter, especially in forte passages or in the low register. “Horns too late!” is an often heard comment from conductors, so producing a precise and direct stopped sound is required, as well as good intonation.

 The Powerstopf is the stopping mute that gives the horn player the means he or she needs to stop easily and in tune. The combination of aluminum and oak results in a direct sound that is identical to the tone color of actual hand stopping.

PowerStopf: Stop different and blend in

Key Features

Perfect intonation

By stopping the horn bell with the hand or a stopping mute the tone rises a half tone, but often these notes are out of tune (sharp). Correcting this problem requires embouchure adjustments that can threaten security. The Powerstopf provides you with secure intonation.

Reproduces hand stopping sound

Working with a stopping mute often results in a brassy tone. The combination of aluminum for direct sound, and an oak “bell” for general color, brings both aspects to a hand stopped-like sound.

Balanced resistance

Resistance is a feature well known by horn players. Hand stopping increases resistance, and sometimes influences the pitch and self-confidence, as well. The Powerstopf is well balanced in all registers.

Comfortable grip

The Powerstopf is designed to handle easily and make for quick changes to open playing.

We usually ship within 24 hours, and depending on your location you will have your Powerstopf within 3 days.

Do I need to stop notes using the F horn, just like I do when hand-stopping??

The Powerstopf can be stopped easily on the B-flat horn side with perfect intonation. You can limit use of the F-horn to the pitches where you would normally use it.

Does the Powerstopf fit in all brands of horns??

The Powerstopf is built a little bit wider than other mutes and provided with a 0.5 mm rubber layer on the shell. We guarantee that it will fit in any bell, or you can return it for your money back.

Why exactly do I need the stopping mute Powerstopf??

Stopping has always been a hard skill to learn. The task of transposing while keeping intonation steady and notes secure can be very difficult. The Powerstopf will help you with these challenges.

Does the Powerstopf transpose automatically??

No, you still need to transpose yourself. But playing a half-tone lower using the B-flat horn, as the Powerstopf allows, will make all the difference ­and is a great feature.
