Where do you get musk?

Excuse me, but could you clarify what you mean by "where do you get musk?" Are you referring to the fragrant secretion obtained from certain animals, such as the musk deer, which has been used in perfumery and traditional medicine for centuries? Or are you asking about the context of Elon Musk, the well-known entrepreneur and innovator who has made significant contributions to the electric vehicle and space exploration industries? If it's the latter, then the answer would be that one doesn't "get" Elon Musk in the traditional sense, as he is a person, not a tangible object or resource. Perhaps you could elaborate on your question to help me provide a more accurate response.
