This in-depth lecture presentation will help you gain a significant edge as a piano tuner and technician. Do you understand what an inharmonicity curve is? How do inharmonicity curves interact across the range of the piano? What does a 6:3, 4:2, or 2:1 octave “look” like when represented graphically? How do coincident partials look when represented graphically? Can you calculate the fundamental frequencies of adjacent notes? Do you understand how to convert between Hertz and cents in different ranges of the piano? Put all this knowledge in your toolkit and you’ll begin to have a much deeper understanding of piano tuning by ear. Learn these concepts and meditate on them as your next ear tuning unfolds. Whether you’re a beginner piano technician and want to ensure you are understanding the foundational theory behind ear tuning or a more experienced technician who wants to update your understanding, this video will be invaluable.
The instructor: Eathan Janney BM, PhD, RPT has 17 years of experience in the Piano Industry, which includes work as a technician in New York, Chicago, Washington D.C., New Orleans, New Jersey, Peru and Hong Kong. He established the acclaimed Floating Piano Factory Apprenticeship Program in 2011 and has been teaching piano technology and helping the advancement of the field ever since. His PhD is in Biology with a concentration on Neuroscience, where his research focused heavily on the analysis of birdsong from a musical perspective. Thus, he has a deep understanding of signal processing and statistical analysis, a wonderful complement to his skills and experience in piano technology. He also has taught through CUNY (the City University of New York) at the City College of New York and Hunter College on topics ranging from biology to statistics. His undergraduate degree is in Jazz Piano Performance from Mason Gross School of the Arts which is the conservatory of Rutgers, the State University of New Jersey.

After my short but full stay in Cartagena, I flew into New York City. I was excited to return to the Floating Piano Factory home base, catch up with friends, and re-discover the beauty of this town. While I was there, I stayed with friends in Long Island, a couple that I came to know through a long chain of music-related moments…
Okay, so there were actually a few more things that happened before I left Arequipa.
I returned to La UNSA to work with the music students once again. This time, we pulled apart a piano so they could see how it’s assembled. How the various pieces all fit together.
This is a rare opportunity. As a student, you don’t usually get the chance to take a piano completely apart, because once you open it up and start poking around, it can get really delicate. There’s a lot you have to learn in order to explore without doing any damage.
But I’ll come back to that.
One of the first important steps in grand piano action regulation is the adjustment of glide bolts. The glide bolts sit at four points distributed lengthwise along the center rail of the grand piano action. They have a tuning-pin-shaped protrusion towards their top, a central threaded portion that allows for up-down adjustment, and smooth rounded bottom. The bottom of the glide bolt both provides support for the center rail of the action and allows the piano to easily glide from left to right when the una cord pedal is depressed. Continue reading
I’ve recently returned from some extensive travels over several weeks. This is why it’s been quiet on the blog for a while, but now we’re back online, and there are many new stories to share. New adventures, new friends, and of course, new pianos.
The next several posts will cover the entire journey, city by city. After departing from Arequipa in early June, I stopped in Lima, Bogotá, Medellín, Cartagena, New York, Philadelphia and Hong Kong—then returned by retracing my path.
In this set of video tutorials Macho and Neway from Floating Piano Factory in Hong Kong show us how to replace hammer return spring cords on a Yamaha U1 upright piano. It is quite common for these cords to wear out and break. In this piano, virtually all of them have become useless! Continue reading
