Biography

Founded in 2020, the Equinox String Quartet brings together four young musicians from North Rhine-Westphalia united by their love for chamber music and the vast world of string quartet literature. In its current formation, with Sabi Yordanov and Christine Schäfer on violin, Lydia Haurenherm on viola, and Cosima Gietzen on cello, the ensemble has been studying since autumn 2022 with the renowned Auryn Quartet in the Master’s program for Chamber Music at the Hochschule für Musik Detmold.

Their artistic development is further enriched through collaborations with musicians such as Benedict Klöckner, Sebastian Schmidt, Anna Heygster, Prof. Ida Bieler, and Michael Denhoff, as well as through participation in international masterclasses, including the International Mendelssohn Festival in Hamburg.

The program of their debut tour, titled “Between Light and Shadow”, was enthusiastically received in October 2021 at venues such as the Kleiner Goldener Saal in Augsburg, the Großer Rathaussaal in Passau, the Mozarteum Salzburg, the crypt of St. Peter’s Church in Vienna, the Kultur- und Liebfrauenkirche Duisburg, the Friedhofskirche Wuppertal, the Event-Theater Schwanenhöfe Düsseldorf, the Silchersaal of the Liederhalle Stuttgart, and the chamber music hall of the Beethoven House Bonn. The program featured Felix Mendelssohn Bartholdy’s First String Quartet and a quartet by Ludwig van Beethoven.

Their current concert tour, “Strings of Fate”, already marks their sixth series in this format and will include, among other highlights, their debut at the Loburg Castle Concerts.
