The German conductor and organist, Constantin Alex, began his musical career in the churches of his hometown Rendsburg. He was fascinated since his earliest childhood by the sound of the organ, got his first organ instruction at the age of 12 with Hans Jürgen Baller, and already in 1976 began to play the organ at the Cathedral Pfarrkirche St. Martin in Rendsburg. From 1980 to 1988 he studied piano (Professor Kretschmar-Fischer), orchestra conducting (Professor Bloemeke) and choral directing (Professor Wagner) at the Musikhochschule Detmold and was at the same time choir director and organist at the Trinitatiskirche in Bad Salzuflen. He concluded his studies with the artistic maturity examination in the subject piano.
Constantin Alex worked first as Repetitor and a Kapellmeister, first in 1988 at the Nationaltheater Mannheim, then in 1989 at the Oper Frankfurt am Main. From there he was engaged since 1992 each year as an assistant of Sir Georg Solti up to his death at the Salzburg Festival and Easter Festival.
In 1993 Constantin Alex was appointed as Professor at the Humboldt-Universität in Berlin, at which he found not only a rich operating field in the choir and orchestra work, but also on organ. Constantin Alex is university music director of the Humboldt-Universität, and in this post is responsible for the studies of practical music making. One big oratorio choir and two symphony orchestras are led by him and at the end of each semester perform symphonic and choral-symphonic music from very different eras of music history. In this post he has found the way back to his original instrument, the organ, and works apart from his conductor activity as organist in concerts and services. In 2002 he was entrusted with the Berliner Universitätsgottesdienste (musical organisation of Berlin University services) at the Marienkirche.
In 2004 appeared CD with "Grossen Orgelwerken Johann Sebastian Bach's ".
