I don't see how this scam can be dangerous if you conduct yourself in a business-like manner. (Selling music lessons IS running a business)
The cheque has been sent for the wrong amount? I will return the cheque to them so they can reissue the cheque for the correct amount. Alternatively (if they prefer) I will present the cheque and refund the difference as soon as the cheque has cleared and the funds are in my bank. I would give the customer the choice, but either way there is no risk to me.
