Answer
Khachaturian composed three symphonies. His first symphony, written in 1934, is characterized by its vibrant Armenian folk influences. The second symphony, completed in 1943, is known for its dramatic and emotional intensity, reflecting the wartime atmosphere of its composition. His third and final symphony, composed in 1947, is a more lyrical and introspective work, showcasing Khachaturian's mastery of orchestral colors and textures.
