... Bring a truly next. The English review below summarizes the meaning and purpose of this collection of "warm-up exercises" together very nicely. I would even go so far as to say even the first 4 bars of "Exercise 1" bring more than a hundred of these "Secret Licks Master Jazz Guitar Play like your hero-etc blah" works of which I also quite a few - still - in have standing at shelf. Already months ago I came across more or less randomly on a video on Youtube of Mr Metheny during a warm-up's for an appearance at a jazz festival. Each of his turns makes musical sense and he demonstrated always new ways what you can do everything from a single idea if they are not just a hollow phrase meaning-exempt on the fingerboard up and runternudelt.
Who has made to exercises of this type a bow will probably do at the beginning a little heavy - the profit to be achieved at, I'd like to say musically-gitarristischer competence, but is enormous.
