Vocal training in the US uses a lot of different languages so most good voice teachers can accommodate singing in French, German, Italian, Spanish, Latin, etc. The training of teachers in the US unfortunately does not include Asian languages which is kinda racist. However, vowels are pretty much the same in most languages so Ellie does do work with people singing in Asian languages as well and has a lot of students in the Hong Kong music industry. It’s good to start on a slow song so she can hear the vowels you’ll need to work with. European and other languages are all a—okay, too.
If you are singing in Mandarin, after learning technique you’ll want to do a few sessions with Mandarin speaker David Lin on our faculty who can help you with putting feelings into the song. This is called “vocal coaching”
