Frank Rauch (born 1961) earned his doctorate in pattern recognition, techniques he now applies to music—in particular, the works of Richard Wagner. For his Music Guides series, he summarizes essential insights, including those from English-language specialist literature on a work's music, making them accessible to the musically interested amateur. Through his audiovisual approach, musical structures are not only explained but can also be listened to as audio examples on www.musicosa.de. So far, the four operas of Richard Wagner's "Der Ring des Nibelungen" have been published. Starting July 2017, "Die Meistersinger von Nürnberg" is also available, both as a Music Guide and as a complete Libretto with leitmotifs, each including an audio CD.
