Upright Piano Tuning with PianoSens

[@paulmccloud]

I shot this video on the fly, sorry for low quality audio. Holding the phone while trying to demonstrate is kinda hard. The point here is that the Pianosens can be used on vertical pianos, not just grands. Notice that sometimes in the high treble, where there are dampers that interfere with the Pianosens, you might be able to put the sensor on the pressure bar and get enough signal to run the app. It is also possible to have the sensor pick up enough string energy from the adjacent strings to pick up the vibrations on the ones you're tuning. A large upright like a U3 is fairly easy fit the sensor, but a smaller upright or even a spinet it is also possible to use the sensor on, though in the high treble the sensor may not fit because of the dampers. Past the dampers, you can fit the sensor below the hammers near the bridge. The signal quality is very good in that position, and it makes the pitch indicator much steadier. Note that tuning each string to the app produces a very good unison result, rather than using your ears, and the sound is very clean. By measuring each string, you can see how close you are to the target, and you'll find that your best effort to tune unisons by ear will only get you within about 3-5 tenths of a cent of pitch. A little extra effort to improve the tuning accuracy pays off with a very clean and clear sound. You can tune unisons by ear of course, which may produce a more "organic" sound that some people prefer. I am not one of them. Also note that I am using Pianoscope, which has a special feature of a "freeze line" that measures pitch during the first second. This is an exclusive feature of Pianoscope, which enables this new level of accuracy. With Pianosens and Pianoscope teamed together, you can create the most accurate, clean and precise tuning possible.
