I grew up in VietNam from 1965 to 1988, I was told that the Soviet Union, USSR piano method .etude books (Ethodu) were the Best. Now , somebody told me that they consisted of 7 volume. I got Volume 5 at home, which I purchased in Viet Nam 25 years ago.
I wonder if they still published the former Soviet Union, USSR Piano Etude Books or not... Where in the world could we purchase them now , since I have nephews , 4 years old that starts learning Piano , now.
Thank you for helping me.
God Bless You All
