The author proposes interesting exercises, especially for those who are beginning to learn the movements of scales and arpeggios. It is good to remember that 'learning' means 'saving', so once you store a kinesthetic movement, move on to another exercise, otherwise the study gets very annoying, never play fast or seek perfection, just learn the movement by studying very slowly.
Another day, someone called me HD, the attempt was to burn me, but I felt flattered, because whenever I comment something, I see people accessing their smartphones to verify the truth, dates, facts, etc. I was very happy, since I never had this nickname, it's just what these books do, store information to be ready for future brain use, this way you choose "to read" by your own Brain HD in real time, but Yottabytes faster than a micro computer or google.
