Sie m\u00fcssen ber\u00fchren. Die Violine 22181 von Holger Krupke entwickelt genau diese Art von Klang. Dieses handgefertigte Meisterinstrument verbindet traditionelle Geigenbaukunst mit einer au\u00dfergew\u00f6hnlich offenen und lebendigen Klangentwicklung. Schon beim ersten Ton entsteht nicht einfach nur Pr\u00e4zision \u2013 sondern Atmosph\u00e4re, Tiefe und musikalische Spannung. Die Ansprache wirkt direkt und fein kontrollierbar. Leichte B\u00f6gen entwickeln W\u00e4rme und Farbe, w\u00e4hrend kr\u00e4ftige Passagen eine beeindruckende Tragf\u00e4higkeit und Pr\u00e4senz entfalten. Genau diese Balance macht hochwertige Meisterviolinen so besonders: Klarheit ohne H\u00e4rte und Dynamik ohne Verlust an Feinheit. Diese Violine reagiert nicht nur auf Technik. Sie reagiert auf Ausdruck und Emotion. Die traditionelle handwerkliche Bauweise sorgt f\u00fcr eine sehr ausgewogene Klangentwicklung \u00fcber alle Register hinweg. Besonders die mittleren und h\u00f6heren Lagen entfalten einen singenden, offenen Ton mit viel Charakter und musikalischer Tiefe. Ob Solo, Kammermusik oder Ensemble \u2013 die Violine 22181 bleibt flexibel und entwickelt dabei immer ihre eigene musikalische Stimme. F\u00fcr fortgeschrittene Spieler. F\u00fcr ambitionierte Musiker. F\u00fcr Menschen, die Musik nicht nur spielen wollen. Sondern gestalten. Fein. Lebendig. Echt. Handgefertigt von Holger Krupke. Traditionelle deutsche Meisterwerkstatt.", "additional_text": "Handgefertigte Meistervioline von Holger Krupke \n Warmer, klarer und ausdrucksstarker Klangcharakter \n Sehr feine Ansprache und gro\u00dfe Dynamik \n Offene und lebendige Klangentwicklung \n Traditionelle handwerkliche Bauweise \n Geeignet f\u00fcr Solo-, Ensemble- und Kammermusik \n Sehr ausgewogene Ansprache \u00fcber alle Register \n F\u00fcr fortgeschrittene und ambitionierte Musiker \n Traditionelle Handwerkskunst \n Made in Germany", "sku": "214\/22181", "mpn": "214\/22181", "ean13": "", "upc": "", "brand": { "@type": "Brand", "name": "Holger Krupke Geigenbaumeister", "url": "https:\/\/musiccraft-instruments.com\/de\/holger-krupke-geigenbaumeister_17" }, "manufacturer": { "@type": "Organization", "id_manufacturer": 17, "name": "Holger Krupke Geigenbaumeister", "url": "https:\/\/musiccraft-instruments.com\/de\/holger-krupke-geigenbaumeister_17" }, "supplier": { "@type": "Organization", "id_supplier": 1, "name": "Migma e.G." }, "main_category": { "id_category": 21, "name": "Violinen", "link_rewrite": "violinen", "urls": { "agent": "https:\/\/musiccraft-instruments.com\/de\/mcc\/mcc_agent\/category?id_category=21&setCountry=0&setCurrency=1", "human": "https:\/\/musiccraft-instruments.com\/de\/violinen-21" } }, "categories": [ { "id_category": 4, "name": "Instrumente", "link_rewrite": "instrumente", "urls": { "agent": "https:\/\/musiccraft-instruments.com\/de\/mcc\/mcc_agent\/category?id_category=4&setCountry=0&setCurrency=1", "human": "https:\/\/musiccraft-instruments.com\/de\/instrumente-4" } }, { "id_category": 6, "name": "Equipment & Essentials", "link_rewrite": "equipment-essentials", "urls": { "agent": "https:\/\/musiccraft-instruments.com\/de\/mcc\/mcc_agent\/category?id_category=6&setCountry=0&setCurrency=1", "human": "https:\/\/musiccraft-instruments.com\/de\/equipment-essentials-6" } }, { "id_category": 7, "name": "Restauration", "link_rewrite": "restauration", "urls": { "agent": "https:\/\/musiccraft-instruments.com\/de\/mcc\/mcc_agent\/category?id_category=7&setCountry=0&setCurrency=1", "human": "https:\/\/musiccraft-instruments.com\/de\/restauration-7" } }, { "id_category": 5, "name": "Highlight", "link_rewrite": "highlight", "urls": { "agent": "https:\/\/musiccraft-instruments.com\/de\/mcc\/mcc_agent\/category?id_category=5&setCountry=0&setCurrency=1", "human": "https:\/\/musiccraft-instruments.com\/de\/highlight-5" } } ], "features": [ { "id_feature": 1, "id_feature_value": 3, "name": "Produkttyp", "value": "Einzelartikel" }, { "id_feature": 15, "id_feature_value": 130, "name": "Besteuerung", "value": "Standard Rate" }, { "id_feature": 9, "id_feature_value": 148, "name": "Instrument", "value": "Violine" }, { "id_feature": 22, "id_feature_value": 173, "name": "Einsatzbereich", "value": "B\u00fchne" }, { "id_feature": 22, "id_feature_value": 172, "name": "Einsatzbereich", "value": "Fortgeschrittene" }, { "id_feature": 22, "id_feature_value": 174, "name": "Einsatzbereich", "value": "Studio" } ], "agent_faqs": [ ], "images": [ { "id_image": 2219, "cover": true, "position": 1, "legend": "Violine 22181 \u2013 Feinheit trifft Charakter", "url": "https:\/\/cdn3.musiccraft-instruments.com\/2219-large_default\/violine-22181-holger-krupke.webp" }, { "id_image": 2223, "cover": false, "position": 2, "legend": "Violine 22181 \u2013 Feinheit trifft Charakter", "url": "https:\/\/cdn3.musiccraft-instruments.com\/2223-large_default\/violine-22181-holger-krupke.webp" }, { "id_image": 2222, "cover": false, "position": 3, "legend": "Violine 22181 \u2013 Feinheit trifft Charakter", "url": "https:\/\/cdn1.musiccraft-instruments.com\/2222-large_default\/violine-22181-holger-krupke.webp" }, { "id_image": 2220, "cover": false, "position": 4, "legend": "Violine 22181 \u2013 Feinheit trifft Charakter", "url": "https:\/\/cdn1.musiccraft-instruments.com\/2220-large_default\/violine-22181-holger-krupke.webp" }, { "id_image": 2221, "cover": false, "position": 5, "legend": "Violine 22181 \u2013 Feinheit trifft Charakter", "url": "https:\/\/cdn3.musiccraft-instruments.com\/2221-large_default\/violine-22181-holger-krupke.webp" } ], "shipping_weight": { "@type": "QuantitativeValue", "value": 1.5, "unitCode": "KGM", "note": "Shipping weight, not product content." }, "variant_model": { "has_variants": false, "variant_count": 0, "default_id_product_attribute": 0 }, "offers": { "@type": "Offer", "offer_scope": "product", "id_product": 99, "id_product_attribute": 0, "url": "https:\/\/musiccraft-instruments.com\/de\/p\/violine-22181-holger-krupke-99.html", "price": 11900.00, "priceCurrency": "EUR", "availability": "https://schema.org/InStock", "itemCondition": "https://schema.org/NewCondition", "seller": { "@type": "Organization", "name": "musiccraft -
