How to tranfer music from my iphone to my ipad without a computer?

I have music on my iphone4s and i want to transfer them to my ipad. I do have a computer but this is the school's ipad so it will not connect to a computer. Also i did not by these songs off of itunes, i transferred them from my computer.

I don't think you should be putting personal items on a school ipad.

Transfer them using Bluetooth
