which other art form inspierd mussorgsky to compose this work

Answer 1

The art form that inspired Modest Mussorgsky to compose his most famous work, "Pictures at an Exhibition," was visual art, specifically a collection of paintings by his close friend Viktor Hartmann. Each movement in the piece is meant to depict a different painting or scene from Hartmann's exhibition. Mussorgsky was deeply moved by Hartmann's art and sought to capture its essence through music.
