text: In orchestral scores since the late 18th century (in the music of Joseph Haydn and later composers), different key signatures may appear simultaneously; some of the different instruments require transposition (e.g., fingering a C to sound a B-flat) because of differences in fingering systems (clarinets, for example) or changes in tube length (in horns and trumpets).
