Read the following excerpt from “The Contest” by Arthur Conan Doyle:
The whole chorus was in full blast, the hummers humming, the shouters bellowing, the tappers hard at work upon the benches, while every now and then came a musical cyclone of "Incomparable! Divine!" from the trained phalanx who intoned their applause, their united voices sweeping over the tumult as the drone of the wind dominates the roar of the sea.
Based on the context of the passage, which definition most clearly fits the word tumult?
