How Is The Piano Tuner
Look at your friends and ask yourselves, how many of my friends are playing piano? Yo will encounter a very little number. In this order, people who knows how to tune a piano is very small. If you ask me, every piano player should learn how to tune it. Since its already a rare instrument, there are not a lot of tuners. And now, I am going to expand this issue to the people who are pianists but doesn't know how to tune or who are not pianist but willing to learn how to tune.
Piano tuning is done by the pegs on the top of any piano. As you will see, there are lots of steel wires bound to those pegs. Tuning is achieved by streching or loosening those wires. Most of the time wires loosen, so when tuning, wires are streched. Of course, you can not tune with bare hands. There is a device for that, consider it as a key.
