I'm taking it and take it back, this booklet is daunting for me at this time, without the help of a teacher while I'm progressing well and I am pleased with Professor without piano or small Pianorama. It is true that these books have nothing to do. With this one, we must understand and work to develop speed. It is a collection for the study, I'll take the time to study because it is clear in his presentation. Even though I have a lot of concepts solfeggios, I forgot.
