The team der re7olution GbR
Inventors Regina Engelhardt und Arne Siebling with Arnd, Nicole und Lilli Mumberg from the „Instrumentenschmiede Mumberg“

Regina Engelhardt

is the managing director of re7olution GbR. She enthusiastically shares her experiences with the new flute head and is responsible for marketing.

From 1989 to 1993, she studied flute at the Music Academy in Kassel and graduated as a „state-certified instrumental teacher“.

Since her school days, she has given many concerts throughout Europe and Japan in various formations.

Since 2000, she has mainly worked as a freelance music teacher for flute, piano and MFE.

Nicole Mumberg

is managing director with Regina Engelhardt and takes care of the organizational work of re7olution GbR.

Thanks to her many years of experience in the instrument forge Mumberg, she virtuously coordinates the different production stages of the newly developed flute bow, which take place exclusively in Germany. In addition, she is available by telephone or on site to provide advice and assistance.

In her spare time, she plays the clarinet in the KSV Baunatal marching band and volunteers as a board member.

Arnd Mumberg    

realised the idea of the new flute head by hand and built the first prototype, which Regina Engelhardt was able to try out thoroughly and happily. Over the course of time, he also developed various hand rests that could make the new flute shape easier to play.

Arnd Mumberg knew very early on that he wanted to become a woodwind instrument maker. After completing his apprenticeship in 1986, he worked in his profession for 15 years until he felt the desire to develop further and become self-employed. In 2004, he successfully passed his master craftsman’s examination in woodwind instrument making.

Whatever the problem, Arnd Mumberg finds a solution.

Arne Siebling

is responsible for marketing the new flute bow.

Arne Siebling first studied guitar as his main subject with Michael Tröster, followed by a degree in artistic maturity. At the same time, he studied clarinet with Wolfram Carlberg as a further main subject.

He has given many concerts in various ensembles and orchestras, but especially with his wife and duo partner Regina Engelhardt. They have given many concerts together, including in Japan. For 13 years he was a guest musician at the Staatstheater Kassel and took part in many productions as a clarinettist, saxophonist and guitarist.

In 2001 he founded the company 2feat. video & music enterprises as a film maker.

Alina Mumberg

has accompanied the development of the new flute head with the greatest interest and her own ideas from the very beginning.

Alina Mumberg initially trained successfully as a carpenter. After completing this first apprenticeship in 2016, however, she decided to begin further training as a woodwind instrument maker.

In 2020, she completed her journeyman’s examination as the best in her year and now professionally supports her father in the workshop of the Mumberg instrument smithy.


Janek Süß    

His many years of professional experience, his high-quality master training as a metal wind instrument maker in Ludwigsburg and his high quality standards make him an excellent contact in the region when it comes to wind instruments.

With a great deal of commitment and ambition, he completed his master craftsman training as the best in his class. In addition to acoustics and scale theory, he was trained in the use of state-of-the-art measuring and analysis systems for wind instruments and has already developed several instruments from scratch.

Svenja Borgstädt

was very happy to hear about the new flute form, as for her, too, a balance to the traditional posture is a great relief.

She started with the flute at the age of 11 with John Hays in Bielefeld.

At the age of 16 she became a junior student in the class of Prof. Michael Faust at the Robert Schumann Hochschule in Düsseldorf.

After receiving her diploma in 2012, she moved to the class of Prof. Sebald, where she graduated with a Master of Music degree in 2015.

Since 2016 Svenja Borgstädt is a flautist in the Army Music Corps Kassel.
