maybe try to approach him with something like "hey I heard you play violin and I kinda want to play violin too but(...) for how long have you played violin?" even if you aren't interested in violin or anything he's interested in, just try to act like you both are very similar and have similar interests and try to smile while speaking to him also look him in the eyes while speaking and make it obvious that you're listening to everything he's saying, the conversation has to be mostly about him bc we're more interested in what we do than what others do. if you say something wrong just joke about it.say something like "da** what am I saying haha"
