Ausgestattet mit sechs Akkorden zu je vier Saiten sowie 25 doppelt besaiteten Melodiesaiten \u00fcberzeugt die Zither durch eine hohe Klangf\u00fclle und ein ausgewogenes Spielgef\u00fchl. Die moderne Akkordanordnung nach dem allgemein gebr\u00e4uchlichen Quintenzirkel erleichtert das Spielen erheblich, w\u00e4hrend die traditionelle Nummerierung der Akkorde erhalten bleibt. Dadurch gelingt auch das Transponieren in andere Tonarten besonders komfortabel. Die Akkordzither wird inklusive Spielanleitung, Zitherschl\u00fcssel und Zitherring geliefert.
