This is Great!
You have gone into great detail and explanation of how to play the piano properly and successfully. This is great! So many beginners start out playing the piano incorrectly or they simply just don’t have a good teacher or both. Good posture, finger placements and being able to read the notes and the music are all important for playing successfully and you go into great detail for any beginner.
I have seen too many beginners getting frustrated and eventually they quit trying to play. I went to piano lessons for 14 years as a child and I can’t tell you how many times I got frustrated and cried because I didn’t understand it. My teacher was a crabby teacher and she got frustrated with me also. I eventually learned and went on to play piano for many events. This is great what you are doing. I think you did a wonderful job on this. I wish there was something like this when I was learning how to play the piano.
My grand daughter has shown interest in wanting to learn how to play and I think this summer when she is here visiting, I will start her out on your site. Thank you for teaching everyone how to play this beautiful instrument!
