I'm not a technician or anything, but I had a question.

My 85 year old upright has kind of slow action, meaning it'd be hard to do a really super fast trill. How would they go about adjusting that?

Oh, forget that comment. I was looking at my piano again, and it just needs tuned and the keys make some noise when I play it. Some worse than others. I need nothing more than to get a skilled technician to look at it.
