Kentaro Nabeshima, RPT
Piano work is my passion: Tuning, regulating and repairing pianos to serve pianists is a great joy for me. I particularly love to service pianos for kids and enthusiastic pianists who share my love of music. I received intensive and comprehensive piano work training from Mr. Richard Bittner, RPT, the owner of the Piano Place in Troy, Michigan, who served as the Central-East regional vice president of the Piano Technicians Guild (PTG) for twelve years. My professional piano work skills are certified by PTG as a Registered Piano Technician (RPT).
Music and science are my two loves. At home, I play piano just for joy. I also have intensive experience in scientific research at the University of Michigan. Although piano work and scientific research look very different, there are common essential components: attention to detail, the precision of the work, and a logical approach to trouble-shooting. To perfect my piano work, I apply the skills that I developed in scientific research in conjunction with my PTG-certified knowledge and skills of piano technology.
Piano tuning - an endeavor for optimum harmony
I was originally trained as a strictly aural tuner, tuning the whole piano entirely by ear. This training led me to "listen" to a piano and perceive the timbre and harmonic sounds that are intrinsic to each individual instrument. Every piano is different, and the tuning process needs to accommodate its unique characteristics. In addition, the physical nature of piano string—steel wire—imposes an inharmonic nature on the piano that makes tuning challenging. Although I now use an electronic tuning device as an aid to make my piano tuning more efficient, aural techniques are essential components of my tuning—and I'm extremely passionate about applying aural techniques to my tuning.
Piano regulation, voicing & repair
In additon to tuning, I provide piano regulation, voicing and repair services. The performance of a piano depends upon the proper adjustment and condition of its action—including dampers, pedals, keys, hammers, and the mechanisms that transmit force from the key to the hammer. The process of adjusting these components is called "regulation.” In some cases, repair may also be necessary. I provide repair services for most of the problems that arise in home use of a piano.
For example, one of the most common piano problems is a sticking key; the key will play, but does not return smoothly to its initial position. There are actually 87 possible causes of sticking keys, and addressing the problem requires professional diagnosis and servicing.
Tone control of the piano is called voicing, and I provide voicing service, too.
