LOTHAR VOIGTLAENDER - PRESENTATION TO THE LECTURE I would like to introduce a composition by Georg Katzer - Mai 1789. Georg Katzer took the subject of the French Revolution - about freedom, equality, and brotherhood - and worked it over in a sarcastic, ironic, intellectual fashion. In this piece, we can register that Katzer doubts freedom and the equality of all people, who are perhaps equal only under the guillotine. It is a virtuosic and particularly thoughtful composition. Georg Katzer - Mai 1789 I would like to further introduce the piece by Lothar Voigtlaender - Dialogue en cause. It was written in 1991 in Bourges and I must say that it bears traces of the period in which it was born. Two years after the revolution in Germany, after the changes, which other East European states were experiencing and anticipating, and a person like Gorbachev was still in personal danger, the overturning of the events still couldn't be ruled out and questions of faith, power, resignation and eruptive rhythm, which can grow into violent processes, these two poles, rhythmically aggressive details, which are contradicted by lyrical snapshots, introverted, and mute to the question of whether the dialogue will succeed or not - as the title says: Dialogue in question, or Questioning dialogue. Lothar Voigtlaender - Dialogue en cause Further I introduce two examples from the production of the Technical University under the direction of Volkmar Hein. The earlier work is from the composer Robin Minard from the year 1988. Work of the electronic studio of the Technical University is characteristic in that in the framework of international exchange programs gifted foreign composers are given the opportunity to work calmly on their compositions and further develop their theoretical expertise. In this framework, Robin Minard from Canada has been working for several years in Berlin already, as has the young Korean lady Un Sung Chin. Both have already presented themselves with their work. Robin Minard is working on his piece Qu'il m'en souvienne... using musical technique possible to carry out very capably on the WAX computers of the Technical University. What takes place is the realization of sound in space especially with in view of time parameters. Sound draws near to us from a great distance, rings out, and fades. For myself, without the appro Robin Minard - Qu'il m'en souvienne... Fortunate coincidences meet in Un Sung Chin's piece - the composer entered sounds from the Berlin area into the computer, analyzed them, took them apart, and brought them together again in a new sound synthesis. Her composition is called El Aliento de la Sombra. She uses sound from one of the largest free outdoor carillons in Europe, the carillon of the zoological garden "Tiergarten" in Berlin, which is right in the center of the city, not far from the Reichstag, and is a favorite park, with a promenade, large expanses, a victor's pillar, and idyllic and artistically very inspirational surroundings. From the sounds of the carillon, Un Sung Chin created her composition El aliento de la sombra, written and recorded in 1992 at Volkmar Hein's. Un Sung Chin - El Aliento de la Sombra
