The Problem:
This video shows that current stability instruction is weak and how important it is for you to understand why a technique works, not just how to perform it.
The Solution:
Look for my next email in which I will share with you how I teach Unisons and specifically, Stability - the ability to set pitches that don't move, even under the hardest of playing - by showing you Why These Techniques Work, so you can figure out what to do when they DON'T, which happens far too often with the traditional ways 
.
You know the old saying, "Give someone a fish and you feed him for a day. Teach them to fish and you feed them for a lifetime"?
Well, it's like that with learning. Tell someone what to do and you teach them how to gets results only when all the variables let it work. Tell them why it works, and you teach them how to get results in all the types of conditions they will encounter.
When I started tuning pianos, people told me to keep my hammer at 12:00, go sharp and ease the pitch down, and don't bend/flex/tilt/flagpole the tuning pin.
Well, that worked "when all the variables agreed".
Problem was, when it didn't work, I had no idea what to do because nobody told me why it worked.
So, I set out to find out.
It wasn't easy. You see, piano tuning is a grassroots kind of activity. Many people just figure it out as they go. There are no schools dedicated to research. They just regurgitate the common knowledge. "It's like black magic", as one of my students, who is an engineer, put it.
So, as an engineer myself, I had to science the heck out of this thing. Using physics, friction, elasticity, elastic deformation, experimental data, tension analysis, and pitch measurements, I was able to develop a theory that helped me reproduce expected results 100% of the time.
I now knew why strings slipped during hard playing and could imagine how to change my technique to one that produced an unstable string would make that string stable!
This was gold for me.
No more being frustrated or confused with ANY piano.
Now, I never feel anxious to tune any piano. When I hear other people complain about Steinway uprights for example, and how hard they are to tune, I just smile, because I know why they are hard to tune, and what to do to make them stable.
It's not easy sharing this information. People are caught up in the years of being told one way of doing something, and now they find it difficult to accept anything that on the surface seems to go against the common knowledge of how to do something.
The problem is, this doesn't go against that common knowledge, it explains why and when that common knowledge works.
But the other thing is it challenges the validity of the instructions.
Now, I know how, when, and why I can use a hammer angle other than 12:00. I also know how, when, and why I can use gentle flexing of the tuning pin during tuning to easily produce a stable string.
For people who have tuned pianos for years believing not only that these techniques would produce poor stability, but that they were wrong, this approach may be beyond their ability to take advantage of it.
But for people starting out, it opens up the way for them to get results fast.
Now, there is a way for students of piano tuning to learn the skill of stability and get it to work on all pianos, no matter the design or condition.
No more blaming the piano.
