Query: Muddled : sacrifices clarity for scope

I finally got round to burning my old copy of this book today . Never really used it . It's just such a dreadfully dull read . How to learn jazz is learn songs . Nail the theory of the song you've learned , and go on to the next song . If there's a point you missed ... ask someone , or post on the web . Don't bother with this book : it's very badly written . The author is not very good at clear argument . Instead he just puts up more and more pointless 'examples ' . Its big , its impressive , its scholarly , .... but for learning to play jazz , it's a dead loss .
