However, there are a few exceptions:
* At the beginning of a sentence: You would capitalize "Didgeridoo" if it starts a sentence, just like any other word.
* As part of a proper noun: If "didgeridoo" is part of a proper name, like a specific band name or the name of a piece of music, then it would be capitalized.
Examples:
* Not capitalized: The didgeridoo is a traditional Australian instrument.
* Capitalized: Didgeridoo music has a unique sound.
* Capitalized as part of a proper noun: The band "Didgeridoo Dreamers" is touring Australia.
