I meant a person who trained to be a chef.
My brother is a Master Chef. He worked as a cook in his teens but wouldn't have called himself a chef because he lacked the experience, practice and skills. However, even if he is cooking burgers in the backyard now... he is still a chef.
I think that trained singers (even if they are in a boy band) can be musicians. That is not to say that everyone who sings is a musician. In the same way that I can play the violin, but I am not a musician because I never took the time to learn the skill.
Ah, it's all semantics and I was in an especially picky mood yesterday.
I just took voice lessons in college and was shocked at the difficulty. I can sing... but I won't ever put in the time to become a singer. Bleh.
