Robert Hopf bietet einen besonders einfachen Einstieg in die Welt der Zithermusik. Dank der \u00fcbersichtlichen Akkordanordnung lassen sich bereits ohne umfangreiche Notenkenntnisse zahlreiche Lieder begleiten und Melodien spielen. Damit eignet sich das Instrument gleicherma\u00dfen f\u00fcr Einsteiger, Musikschulen und ambitionierte Hobby-Musiker. Die Zither verf\u00fcgt \u00fcber sechs Akkorde mit jeweils vier Saiten sowie 25 einfach besaitete Melodiesaiten. Die neue Generation der Akkordzithern basiert auf der heute gebr\u00e4uchlichen Akkordanordnung nach dem Quintenzirkel, wobei die traditionelle Nummerierung der Akkorde erhalten bleibt. Dadurch wird das Spiel deutlich intuitiver und ge\u00fcbten Spielern das Transponieren in andere Tonarten erheblich erleichtert. Geliefert wird die Akkordzither inklusive Spielanleitung, Zitherschl\u00fcssel und Zitherring. Das Instrument ist in den Farben Schwarz, Natur und Mahagoni erh\u00e4ltlich. Schwarze Zargen und Boden sowie der dekorative Rosen-Siebdruck verleihen der Zither ein klassisches und hochwertiges Erscheinungsbild.", "additional_text": "Akkordzither mit 6 Akkorden \n Je 4 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.
