Here is the superb Reyburn CyberTuner in action – I originally learned to tune aurally and have been using the CyberTuner software as it has developed since 2010. It is a superb tool to get the most accurate tunings on whatever styles of piano I come across.
It has the benefits of being hugely accurate, consistent and reliable. It also calculates how much over to pull strings to settle at the correct pitch and tuning with the visual aid allows you to assess the stability of the piano as you are tuning.
