      "full_description": "Die ersten Jahre entscheiden oft dar\u00fcber, ob Musik bleibt. Ob aus \u00dcben Leidenschaft wird.   Die Violine 21871 von Holger Krupke wurde genau f\u00fcr diesen Einstieg gebaut.   Dieses hochwertige Einsteigermodell verbindet eine angenehme Ansprache mit sauberer Klangentwicklung und einem Spielgef\u00fchl, das motiviert statt frustriert. Denn gerade Anf\u00e4nger brauchen kein kompliziertes Instrument \u2013 sondern eines, das musikalische Entwicklung unterst\u00fctzt.  Die Violine spricht leicht an und entwickelt einen warmen, klaren Klang, der auch bei den ersten \u00dcbungen angenehm und kontrollierbar bleibt. Gleichzeitig bietet das Instrument genug klangliche Offenheit, damit Spieler mit ihren F\u00e4higkeiten wachsen k\u00f6nnen.   Eine gute Anf\u00e4nger-Violine spielt nicht f\u00fcr dich. Aber sie macht Lernen deutlich sch\u00f6ner.   Die traditionelle handwerkliche Verarbeitung sorgt f\u00fcr eine ausgewogene Balance zwischen Stabilit\u00e4t, Ansprache und Klangfarbe. Dadurch eignet sich die Violine ideal f\u00fcr Musikschule, Unterricht und t\u00e4gliches \u00dcben.  Besonders wichtig bei einem guten Einsteigerinstrument: Es darf nicht billig wirken. Die Violine 21871 vermittelt genau das Gef\u00fchl eines echten Instruments \u2013 nicht eines kurzfristigen Lernwerkzeugs.  F\u00fcr Anf\u00e4nger. F\u00fcr Wiedereinsteiger. F\u00fcr Menschen, die Musik endlich selbst machen wollen.   Der erste Ton muss nicht perfekt sein. Aber er sollte Spa\u00df machen.   Gefertigt von Holger Krupke. Traditionelle Instrumentenbaukunst aus Deutschland.",
