Dank der \u00fcbersichtlichen Akkordanordnung eignet sich das Instrument sowohl f\u00fcr Einsteiger ohne umfangreiche Notenkenntnisse als auch f\u00fcr erfahrene Zitherspieler. Ausgestattet mit sechs verst\u00e4rkten Akkorden zu jeweils sieben Saiten sowie 25 einfach besaiteten Melodiesaiten erzeugt die Zither einen besonders vollen und tragf\u00e4higen Akkordklang. Die moderne Akkordanordnung nach dem allgemein gebr\u00e4uchlichen Quintenzirkel erleichtert das Erlernen neuer St\u00fccke erheblich. Gleichzeitig bleibt die traditionelle Nummerierung der Akkorde erhalten, wodurch auch das Transponieren in andere Tonarten komfortabel m\u00f6glich ist. Zum Lieferumfang geh\u00f6ren eine Spielanleitung, ein Zitherschl\u00fcssel sowie ein Zitherring. Die Akkordzither ist in den Farben Schwarz, Natur und Mahagoni erh\u00e4ltlich. Schwarzer Boden und Zargen sowie der dekorative Rosen-Siebdruck verleihen dem Instrument eine klassische und hochwertige Optik.", "additional_text": "Akkordzither mit 6 verst\u00e4rkten Akkorden \n Je 7 Saiten pro Akkord \n 25 einfach besaitete Melodiesaiten \n Akkordanordnung nach dem Quintenzirkel \n Traditionelle Akkordnummerierung \n Inklusive Spielanleitung \n Inklusive Zitherschl\u00fcssel und Zitherring \n Farben: Schwarz, Natur oder Mahagoni \n Boden und Zargen in Schwarz \n Mit Rosen-Siebdruck \n Hersteller: C.
