Final answer:
Modernist music, exemplified by Stravinsky, is characterized by a significant emphasis on percussion instruments, reflecting a shift in orchestral composition.
Step-by-step explanation:
Modernist music, as represented by Igor Stravinsky, is marked by an increased emphasis on the percussion family of instruments. During the modernist era, composers like Stravinsky sought new textures and timbres, leading to a more prominent role for percussion instruments within the orchestral setting. This reflects an evolution from the dominance of strings and woodwinds in earlier periods to a more diverse and experimental approach in instrumentation.
