These are the exercises I have been using for quite a few years now and continue to do so on a daily basis (or at least each time I practise). I used to attend the workshops run by David Heyes and we always started with these exercises (and others). I am sometimes skeptical about method and exercise books, but not in this case as David himself uses these exercises also on a daily basis.
Eventually, I took private lessons with David and finally realised, with method, good technique, and muscle memory, it was possible to hit any and every note, which we did from more than one approach. I also learnt how to work out the best [for me] finger positions, to which I could transfer this skill to both guitar and piano, with the same thought process. Although I have the book, and one or two others, all the exercises are ingrained into my memory and for every practise time, these take priority, scales and arpeggios next, pieces and fun-stuff last.
