Estabilidad de la afinación requiere estudio y práctica
Tuning stability requires study and practice
Comments by educator/tuner/mechanical engineer Mark Cerisano:
The video is good. It explains a lot of good things, such as humidity control.
To improve stability, and not just being able to make a string stay at pitch, but to do it efficiently, we need to change our understanding of exactly what is going on with tension, etc. in the piano while we are tuning.
To learn more, watch the videos on howtotunepianos.com.
