Q: I tune my piano about twice a year and it costs $100 per  tuning. How long would the Self-Tuning Piano take to pay for itself?
A: Justifying the cost of the Self-Tuning Piano based on how many times you currently tune your piano is like justifying the cost of a cell phone based on how many dimes you would have spent in a pay phone.  With the Self-Tuning Piano you can tune your piano every day--even after every song you play! If you think about the potential cost of $100 every time you push that button, the system pays for itself in days, not years.
Q: I understand the piano is tuned by warming the strings with electricity. Are there any fire hazards or electrical dangers to me or my pets?
A: No. The median temperature of the strings is about 95 degrees Fahrenheit. The keys in your pocket are hotter than the self-tuning strings get.  And the voltage required to warm the steel piano strings is minuscule: about 1.5 volts (like a flashlight battery).
Q: My tech tells me that there is much more to tuning a piano than bringing them all to a “theoretically correct” pitch.  They must also be “stretched” and tuned “aurally”.
A: Exactly. That’s why the Self-Tuning Piano “stores” an actual hand-tuning. This tuning is simply repeated every time you push the button.  There are no theoretical calculations involved.
Q: I can see how warming the strings would expand them and flatten them in pitch, but I don’t understand how you raise the pitch for tuning.
A: When the system is installed, your tech will first instruct the circuit to warm all the strings, then he will manually tune the piano just how you like it. When the system is switched off, the strings will cool to room temperature and become a little sharp (higher in pitch). Since all the strings are sharp to begin with, all tuning is accomplished through warming and lowering the pitch.
Q: What is the tuning range of the system?
A: The available tuning range is rated as a whole for the entire piano. It has a capability to tune a total of 6000 to 7000 cents (depending on room temperature). That’s about 30 cents per note average. But remember that this is a total available "pool" of tuning range. For example, if a particular note takes 15 cents to tune, then it only used 15 cents of the average 30 cents available, so 15 cents weren’t used and would be available for use by another note if it need more than 30 cents to tune.
Q: Will warming the strings harm them?
A: No. Metallurgical effects such as "creep" occur at many hundreds of degrees fahrenheit. Warming the steel strings to 95F has no adverse effect on the strings at all.
