Dearest Masters Paolo and Simone,
I have just subscribed to your wonderful website!
As I already mentioned in my introductory letter, your videos have provided me with a fundamental contribution to the theoretical preparation regarding the complex functioning of our instrument in view of the Eighth Grade exam that I have the day after tomorrow. However, I have a major gap that I haven't been able to find anywhere: namely, the mechanics of the various piano PEDALS!!
If you feel like it, it would give me immense pleasure to hear a video explanation regarding the various types of pedals found, their different functions, their relationship (I imagine) with the dampers, and their adjustment (the pedal commonly called the "una corda" has just broken on me and I would like to fix it myself, or at least understand what happened and why it suddenly stopped working).
In particular, I would like to understand how the sostenuto pedal works, and why it is only found in grand pianos (is it related, as explained in your fifth video, to the geometry of the mechanics? Does it rely on gravity and therefore cannot be installed on an upright piano??).
Thank you a million anyway for everything, you are truly legendary and I fully support this beautiful project that you are carrying forward (I am advertising it among my pianist friends)!
Giacomo
