Native asians that I have talked to have described English as a very emotional and musical language. One Vietnamese man said that before he learned the language, it sounded to him as though English speakers were singing when they talked to each other.

I think that this is because differences in words due to pronounciation of vowels tend to be more subtle in Asian languages than they are in English, making speaking styles more restrictive. Then again, I'm talking out my ass here (also a musical sound). What we need is a cunning linguist to clarify things for us.
