When improvising， what your mind hears is more often than not determined by what your body can reproduce on your instrument。 Much of your conception as an improviser is determined by your technique。 If you cant play certain types of ideas， you are simply not going to conceive of them while you are improvising。 Even if you could， it wouldnt matter， since you couldnt play them anyway。 Serious chops building technical studies for single note lines and chords。 Plus， the examples feature a lot of harmonic content。 This book is about much more than technique。。。I believe this would be a great addition to any jazz guitarist's library。 In standard notation only。
