I've been paying a tutor to teach me korean for a year with a twist. I told my tutor to not teach me anything, all I want is honest feedback about how I sound. What accent I make and how to say things a certain way. She just listens and tells me the impression I give off.

With her feedback I am able to self adjust to reflect my personality when I speak Korean.

Personally, I feel like getting a tutor to "teach you" something in the artsy space may slow down your search to find your own voice that resonates with you. Maybe you can pay a tutor to just "listen to you" and tell you what you sound like to the other person.

On the other hand, if your goal is to just to imitate other singers, I would suggest getting a tutor to teach you like many other are suggesting.
