Answer:
False.
Step-by-step explanation:
Classical music is often distinguished by the wide use it makes of musical instruments of different timbres and tonalities, creating a deep and rich sound. The different movements of classical music were affected mainly by the invention and modification of these instruments over time. Although classical music does not have a "set" of instruments necessary for certain standards of its execution to be fulfilled, composers write their works with different instrumental ensembles in mind. Vocal parts are not a mandatory element, but they can complement bringing more meaning to the work.
