Ooga booga's Things

I need help confessing to someone.There's this guy who's in band with me I dont know him and he doesnt know me but sometimes we'll make eye contact or catch him looking at me or him looking at me.I don't know something about him really attracts me. I want to ask him if he wants to start talking or just plain out tell him that i like him but if i do i don't know how to .Does anyone have any advice or tips to help me figure this out :m
