<html> Call a piano technician for the best hands-on advise. You will learn more 'in person' than trying to figure thinks out on your own.  There are probably many things awry with your piano which can be tended to by someone knowledgeable.  This is where experience counts. If you are serious about learning more, attend a few Guild chapter meetings and join. There's a reason for not having a piano department at Home Depot.  It's not a 'do-it-youself' job.
