I can't find my key and/or the tempo is not right.
Can you change these for me?

We can do this for you. We will charge $10 U.S. for such a change. Simply provide us with the key(s) or metronome marking(s) you need, and we will get it done for you. We will let you know how quickly we can get to it as well, if there is any kind of backlog in work to be done.
