"On behalf of expertvillage.com, I am Tom Flowers, owner of Well Tempered Piano Tuning and I am here today to talk to you about piano tuning and maintenance. We are going to take a look inside now of the piano and moving from the players position forward. We have a harp, this large metal cast iron typically which is what this is. It is coated in super bronze oxide. We have tuning pins for all roughly 225 strings. As you see the strings begin with single strings into double strings into triple strings on up to the top of the piano. Strings are not individual. This string begins at this pin, comes around a hitch pin down here and returns to the second pin. So it is actually one piece of piano wire strung at two points. The small objects here are called agraphs. These keys keep the strings at a particular level and distance from each other. These are called the head bar or pressure bar and this puts pressure on the strings and gives them the proper down barring coming up to the pins. These are the dampers. These are what comes down once they are activated and stops it. These are simple things happening and sometimes not so simple operation as there are many parts governing those processes. It has a bridge with strings guiding over to the hitch pin and everything is over a soundboard which is typically made of ___ or engleman's spruce. In this case, it is probably engleman. It does have some cracking. Kind of difficult not to have cracking in nearly a hundred years of southwest dry air. It may not be a problem. Often it is said that if a piano has a cracked soundboard, that it is over but that is really not the case. If you cannot hear the crack and it is not particular wonderful to look at but it isn't a problem. "
