She received her first violin lessons at the age of 4 and switched to the viola five years later. At the age of 11, she was accepted as a junior student in the class of Prof. Lukas David at the Musikhochschule in Detmold, where she later continued her studies.

Her special love is chamber music, which was formed at a very early age by collaboration in a quintet with her sisters. During her studies in Detmold, she gave numerous chamber concerts with Lukas David, Tibor Varga, Irene Güdel and Jost Michaels, among others, in Switzerland, Austria, France, Spain and Israel. Today, Irene Lachner can look back on 45 years of chamber orchestra experience.

She started as a violinist at the age of 6 in the orchestra of her first teacher A.W. Torweihe. Her path led her via the Tibor Varga Chamber Orchestra, the Deutsche Bachsolisten and the Karl Münchinger Chamber Orchestra to the Württemberg Chamber Orchestra Heilbronn 25 years ago, where she has been solo violist since 1989.
