We have been using the professional services of Mr. Norio Kawato of San Jose, CA since February 2010, when our new Yamaha Disklavier DC6MK4 was due for tuning. He was recommended to us by the Yamaha Peninsula Music Center where we bought the piano.
Our first impression was quite favorable and we decided to do the second free tuning offered by the vendor with the same specialist.
The second time around, I gave him an unusual challenge when I measured with a force-meter the force applied on the damper pedal. The force was larger than the one measured in vendor's shop on other pianos (my own research) and the pedal made a louder noise than the standard. I had addressed the same question with the official Yamaha support technicians and had they had sent me a replacement spring, which was softer and expected to create a smaller force in the pedal.These people knew Mr. Kawato because he had been trained by Yamaha Corporation. Mr. Kawato promptly accessed the respective place in the piano and determined that I already had the right (softer) spring there.
Then, in a matter of 5 minutes or less, Mr. Kawato made the piano in pieces (which scared my wife and me!), spread them around the room and reached deeply into piano's internal mechanics where he found a loose screw from the factory. He tightened it and that did the trick. Then Mr. Kawato quicky made the piano back in one piece (which calmed us down!) From that moment on, we settled to Mr. Kawato as our preferred piano tuner and will call him from wherever he might be in the future.
Further on, my wife and I discovered that Mr. Kawato is a fine person, with whom we can talk various subjects of mutual interest, Japan being the preferred one for us - while he continues to do his job. We hope we have not bothered him too much with our conversation. Last time we had him in our house, Mr. Kawato upgraded our piano's operating system, which took about one hour due to the low speed of our connection. He did everything on his own time and to our satisfaction.
In conclusion, if you are looking for a professional piano tuner - any acoustic piano or Yamaha disklavier - you have him in Mr. Norio Kawato of San Jose, CA. read more
