Gerd Zacher – Realisation & Cembalo
Born in Meppen an der Ems, 1929, he studied at the Nordwestdeutsche Musikakademie in Detmold (1949-1952) and in Hamburg (1952-1954). Studies with the Reger student Fritz Lubrich (in Kattowitz), the Busoni student Theodor Kaufmann and the Karl Straube students Michael Schneider and Hans Heintze. Zacher participated in the Summer Workshops in Darmstadt in 1952 and 1953. Played his first organ recital in Hamburg 1952 (Messiaen’s cycle Les corps glorieux). He performed as an organ soloist in Europe, USA, Australia and Japan. Cantor and organist at the German Evangelical Church in Santiago, Chile (1954-1957) and at the Lutherkirche in Hamburg-Wellingbuettel (1957-1970), where he also served as the Music Director. In 1970 Zacher accepted a position as Professor for Sacred Music at the Folkwang-Hochschule in Essen, where he taught until 1991. Zacher played an important role in the revival of the organ as an instrument for avant-garde composition. Zacher’s willingness to deeply explore his instrument has lead to the development of new performance techniques and sounds. Among the composers who composed for him are John Cage, Mauricio Kagel, Gyoergy Ligeti, Dieter Schnebel and Isang Yun. Zacher’s intense interest in the organ and its traditional role deeply influenced the current interpretation of Bach’s music – through publications, seminars and the cycle Die Kunst einer Fuge – Bachs Contrapundtus I in zehn Interpretationen (1968/69). Gerd Zacher passed away in Essen, June the 9th 2014, at the age of 84 years.
