Bis pl\u00f6tzlich der erste Ton funktioniert. Und genau dort beginnt dieses Buch. \u201eMundharmonika f\u00fcr Anf\u00e4nger\u201c ist kein trockenes Lehrbuch voller Theorie, die niemand wirklich spielen will. Es ist ein direkter, verst\u00e4ndlicher Einstieg f\u00fcr Menschen, die endlich selbst Musik machen wollen. Ohne Vorwissen. Ohne Notenpanik. Ohne dieses unangenehme Musikschulgef\u00fchl. Stattdessen geht es hier um das, was wirklich z\u00e4hlt: Spielen. Ausprobieren. Fehler machen. Besser werden. Denn genau so entsteht echte Musik. Das Buch f\u00fchrt Schritt f\u00fcr Schritt in die Welt der Blues-Harp ein und vermittelt die Grundlagen so, dass man nicht nach f\u00fcnf Minuten aufgeben m\u00f6chte. Erste Melodien, einfache Rhythmen, Atemtechnik und die typischen Blues-Harp-Sounds werden verst\u00e4ndlich erkl\u00e4rt und direkt praktisch umgesetzt. Und pl\u00f6tzlich passiert etwas Verr\u00fccktes: Aus einzelnen T\u00f6nen wird Musik. Genau deshalb ist dieses Buch perfekt f\u00fcr Anf\u00e4nger, Wiedereinsteiger oder Menschen, die sich jahrelang eingeredet haben, sie k\u00f6nnten kein Instrument lernen. Hier geht es nicht um Perfektion. Sondern um diesen einen Moment, in dem Musik pl\u00f6tzlich etwas Eigenes wird. Abends auf dem Balkon. Am Lagerfeuer. Zwischen zwei stressigen Tagen oder nachts um halb eins mit einer neuen kleinen Melodie im Kopf. Spiel. Nicht nur rum. Geschrieben f\u00fcr Menschen, die Musik nicht nur h\u00f6ren wollen. Sondern endlich selbst machen.", "additional_text": "Einsteigerbuch f\u00fcr Mundharmonika und Blues-Harp \n Ideal f\u00fcr Anf\u00e4nger und Wiedereinsteiger \n Verst\u00e4ndliche Schritt-f\u00fcr-Schritt-Erkl\u00e4rungen \n Praxisnah statt trockener Theorie \n Erste Melodien, Rhythmen und Atemtechnik lernen \n Perfekt zum Selbstlernen geeignet \n Motivierender Einstieg ohne Musikschulgef\u00fchl \n Geeignet f\u00fcr diatonische Mundharmonikas \n Geschrieben von Volkmar Kramarz", "sku": "865\/41004", "mpn": "865\/41004", "ean13": "", "upc": "", "brand": { "@type": "Brand", "name": "C.
