I have a somewhat stupid question, and I don’t know if it has been asked before: Can you maintain pitch accent when you’re singing, screaming, or sobbing?

For example, if I am yelling at someone, everything I utter will automatically be high-pitched, so how will people infer the meaning of what I am shouting?

Similarly, if I am singing, the meaning may of what I sing could be altered because the song may require a particular syllable or word to be high-pitched when it’s not or low-pitched when it’s not.

How do people fluent in Japanese handle situations like these? I am quite sure that doing so in Mandarin would be a nightmare.
