Der zentrierte Viola-Kinnhalter von Wittner wurde entwickelt, um genau dort anzusetzen. Durch die mittige Position entsteht eine nat\u00fcrliche Balance zwischen Instrument und Spieler, wodurch Haltung und Bewegungsfreiheit harmonischer wirken k\u00f6nnen.  Die leichte Konstruktion und die hautfreundlichen Materialien sorgen daf\u00fcr, dass auch lange Proben oder Konzerte angenehmer bleiben. Typisch Wittner steht dabei nicht Technik im Vordergrund \u2014 sondern das Gef\u00fchl, ungest\u00f6rt spielen zu k\u00f6nnen.   Weniger Spannung. Mehr Raum f\u00fcr Klang.  \n \n Zentrierte Ausf\u00fchrung f\u00fcr Viola \n Ausgewogene und nat\u00fcrliche Spielposition \n Besonders leichtes Design \n Hautfreundliche Materialien \n Hoher Komfort bei langen Sessions \n Qualit\u00e4t von Wittner",
