After extensive musical education, Karel Berman started his career as a bass singer of opera in Opava.[1] In March, 1943, Berman was deported to Theresienstadt, where he took part in cultural life as a singer, composer and director.[2] On 11 July 1944, for example, he and Rafael Schächter produced the "Four songs to words of Chinese poetry" by Pavel Haas for the first time.[2] In 1944 he composed Suite Terezin in three movements ('Terezin', 'Horror', and 'Alone'); a work which musicologist Bret Web described as "a rare in situ tone portrait of life in a Nazi camp".[3]
