The internet is completely overwhelming for classical piano students looking for information. Some recommendations are always helpful.
The "Pianist" magazine has a series of very helpful articles which support piano lessons. I recommend their channel.
Graham Fitch, the presenter in many for the channels videos has a wonderful site of information as well.

I'm a professional pianist and music educator in West Toronto Ontario. I'm also a devoted percussionist and drum teacher.
