Read it through once

But the music does more than reflect the life of mirth and folly which was led in the gay and voluptuous city. It has an undertone of sadness; its lesser thirds so plaintive, its sixths diminished, sigh on sigh, tell the votaries of pleasure something; its suspensions, its solutions, its commiserating sevenths, awaken in them the question of their hold on life. That question the music answers.
