It's possible you're thinking of something else. Here are some possibilities:
* Metis (Greek mythology): Metis is a figure from Greek mythology who was the first wife of Zeus. She has no specific sound associated with her.
* Metis (music): "Metis" is not a common word in music. There might be a specific band or song called "Metis", but without more context, it's hard to say what it would sound like.
* Metes (a unit of measurement): "Metes" is a unit of measurement used for distances and areas. It doesn't have a sound either.
Could you please clarify what you meant by "metis"? Perhaps you can tell me:
* What context are you thinking of? (Music, mythology, etc.)
* What makes you think "metis" has a sound? (Did you see it somewhere, or are you trying to find music with that name?)
Once I have more information, I can try to give you a more helpful answer.
