"The symphony is scored for piccolo (fourth movement only), two flutes, two oboes, two clarinets in B♭ and C, two bassoons, contrabassoon or double bassoon (fourth movement only), two horns in E♭ and C, two trumpets, three trombones (alto, tenor, and bass, fourth movement only), timpani (in G-C) and strings."
Do you see any vocal parts in that description?
