I have perfect pitch in that I can tune a guitar perfectly without aid. That is not to say that A is going to be 440, but it will be in tune to itself, and highly playable. But now that I have bought a piano it all defaults to that.
When it comes to playing with others, it has to be in real tune. But alone, for playing alone I can do it.
N Cook, you should try to learn how it is suposed to sound. That would be an achievement. I had a buddy with a severely out of tune piano, I really wanted to tune it. It had been welded. It was out bad.
I have a portable keyboard which I would've tuned to first, every string, and then set the offsets.
With a keyboard you do not have to deal with that. Just set the notes.
Have fun with it. If you're around Cleveland I might like to watch or even help. If not, so much for that.
If you are trying to tune this thing you should have a pretty good idea of how it should sound. After one reference you should have it. I did not say it was easy to do that way, but it is possible. How did the first guy who invented the thing do it ?
