Koessler composed over 130 works, including an
opera, two
symphonies, symphonic variations for orchestra, a
violin concerto, two
string quartets, a
string quintet, a
string sextet, a
piano quintet, a suite for piano, violin and viola, and a
mass for female choir and organ. He also set
psalms to music. However, as a result of his erratic way of living, a large number of his compositions were lost, or found themselves only being played in private hands. Koessler's chamber music has been highly praised by several commentators, including the eminent chamber music scholar
Wilhelm Altmann, who has singled out Koessler's Second String Quartet and his Trio Suite for Piano, Violin and Viola for especial praise. ==Bibliography==
