I thought I could just "continue" from Grade 5 and do Bach, Chopin etc but I encounter difficulties. I am currently using 2 books from my old collection: "Hours with the Master Vol.1 Dorothy Bradley" and "Tuneful Graded Studies Vol.3". What grades do you think those books are?
Should I discard those books? If yes, what other kinds of books should I get?
And, how should I improve my technique given the fact that I should have master them but I "didn't"?
Also, is it advisable to just go for more challenging pieces like Bach, Chopin etc, hoping those pieces can improve my techniques? (considering the fact that I haven't really tried out those pieces dispite the Grade 5 status, and also the fact that most members here seem to be able to do difficult pieces even though they are just low-intermediate levels)
Lastly, I could only practice an hour a day (or sometimes none), does this play a big part for me not playing well too?
