Only when sound is becoming a real experience, the SONOR quality standard is met. From precision craftsmanship musical expression is shaped.    

For decades SONOR has supported the constant improvement of percussion instruments on a scientific level. The close cooperation with research institutes, renowned musicologists and leading artists builds the basis for these efforts. Several groundbreaking developments were made possible by these mutual activities. An example is the optimization of the resonance properties of drum shells. In the area of mallet instruments, vibraphones, metallophones and glockenspiels SONOR has introduced major improvements in quality standards. Also concert and marching percussion instruments have seen considerable further developments.
