Night on Bald Mountain Night on Bald Mountain (Russian: Ночь на лысой горе, "Noch′ na lysoy gore" ), also known as Night on the Bare Mountain, is a series of compositions by Modest Mussorgsky (1839–1881). Inspired by Russian literary works and legend, Mussorgsky composed a "musical picture", "St. John's Eve on Bald Mountain" (Russian: Иванова ночь на лысой горе, "Ivanova noch′ na lysoy gore" ) on the theme of a witches' sabbath occurring on St. John's Eve, which he completed on that very night, 23 June 1867. Together with Nikolay Rimsky-Korsakov's "Sadko" (1867), it is one of the first tone poems by a Russian composer.
