How to make when u click a gui it plays music for the player and switching camera?

The title says it's all ^ please help

Look, Scriptinghelpers is a site where people need help with scripting, if you can't script then don't bother coming to this site asking for help, because when you ask a question, you are generally asking for help dealing with a error/problem that you encountered while scripting, other times. there are questions like "What is pcall?" those are not requesting anything. the point is, you shouldn't request stuff from others, you should make your own scripts and then if you encounter a error then come back. at least go try script it yourself or read the rules/community guidelines of this site.

and also, from this question I can see that you're asking for way too much than you can handle. so don't always try to make stuff you don't know how to make.
