Getting straight to the point; this book has too much waffe/padding and not much substance. Too many references back to the Inner Game of Tennis (and Work) which don't make you feel any better that a technique has been lifted from one subject area and then re-applied to another (we are not playing tennis, this is music). Constant references to the words "Inner Game" like it is a kind of magic utterance when all we are talking about here is essentially keeping focussed and beating nerves and more pyschobabble about "Self 1" and "Self 2" (and I'm not down on psychology but it felt like the point was being laboured here due to lack of material). I went on a music workshop two months ago that I learnt tons more from; essentially if you want to win the "inner game", master your instrument, build up tons of muscle memory, scales and arps in all keys - start slowly and build, circle of forths, PRACTICE THINGS SLOWLY before playing them fast, master improvisation; start by playing root notes in bars, then adding the 3rd,the 5th, then the 7th, play with lots of other musicians to up your game, play music you love and enjoy it. You will be a better musician if you do these things. You just saved yourself £7.99.
