I used to take piano lessons for several years. I got up to level 5 in the Piano Adventures series if that helps you know my experience. It’s been a couple of years since I’ve played and I would like to become an experienced player without the help of lessons. What is a good book that can help me learn quickly and get me to a fairly high skill level?
do you still have your books and the pieces that you used to play?
if you have them, go back and read through them
try playing some songs from here and there
if you have difficulties playing some songs from a specific level, try playing the songs from the previous level
practice a lot and it’ll come back to you
good luck!:)
