Pictures at an Exhibition is a piece of music for solo piano composed by Modest Mussorgsky in 1874. It is Mussorgsky’s most famous solo piano work and often played by virtuosos to show how good they are. Many years after Mussorgsky’s death, Maurice Ravel made an arrangement of the piece for orchestra. This version, by a Russian composer and a French arranger, is how people usually hear the music today.
