u/BlueBass626

so I kinda need advice, I’m very interested in music and would like to make my own band. I’m considering my nephew on drums and me on guitar. Here’s the problem, I need a bassist,keyboardist,and vocalist. The only person I know who sings is my cousin. Here’s the problem, we don’t have a good relationship at all. She’s pretty good at singing from what I heard but idk if she would even be interested!? How do I approach her?
