Hello, I am Malcolm from the Piano Workshop Reigate, Surrey, UK and I am here for About.com to give you a few tips on how to spot piano damage.If there is any damage on the casework, the outside of the piano, if there are scratches or knocks, you will be able to just see that. When looking at second hand pianos one of the first things you need to do is, well, obviously to do a visual inspection, but also to play every single note to make sure it works and its sounds in tune.If some of the notes do not work or you cannot play them twice in a row like that, which is called repeating, then there might be some internal damage which you might not be able to see. In that case, if there is a problem with it, you need to get a piano tuner in, or a piano technician to have a look at the piano and see what is going on.When looking at a piano you will be able to see the strings on a grand piano. Make sure there are none broken. In an upright piano it is a bit, little more harder. Lift the top lid up and have a look inside. If the string is broken, you will be able to spot it right away.There is a couple of other things to look for when checking a piano over. One sign is have a look for signs of woodworm, which could be underneath or behind it and also for sign of moth, which would be inside. Looking at a piano, especially a grand piano, make sure all the legs are fitted correctly and the whole piano feels stable. Also, check the keyboard, you could have, if you have got ivory keys they could be lifting off and it could be chipped. And the same with plastic keys, can be chipped or lifting off as well.With all these problems that you do come across in the piano, everything is repairable. So, again, go to a reputable piano tuner, technician and ask his advice on keeping parts repaired. If you keep your piano regularly tuned, then the tuner will also take care of what is going on inside your piano. The piano will last you a whole lifetime.My name is Malcolm, I am at the Piano Workshop, Reigate, Surrey, UK, for About.com.
