Thank you for sharing your wisdom. After 2 years of piano lessons at 10 years old, I am finally back after almost 50 years. I never quit playing piano. In fact, I have performed for several years. But I knew that I was lacking a lot of key elements in my playing, that only a good instructor could give me. I am finally catching up with all those things I should have learned years ago: proper technique, scales and arpeggios in all the keys, sight reading, etc. I am working hard and thrilled to be really learning again.
Your website is such a great wealth of information on all-things-piano. I visit your site weekly to see what is new.
