Getting A Pitch Pipe

I'm so excited! I just got my first pitch pipe for Lads to Leaders and I can't wait to use it. With it being my first pitch pipe I'm not used to it and I don't quite get how it works but I will get there. I have wanted a pitch pipe for awhile but I could never find one. I have seen how it has helped other people do a song so I am pretty sure it can help me too!
