I recently bought a book on jazz harmony i have over 200 books so I felt this wasnt going to be all that deeper trhen what i already have
but whoa was i wrong this book has a lot of info in it and it allows you to open up and get your technique tight.
each concept given you are to be able to play at 100 bpm with no mistakes through the cycle of fifths and it breads down open chords closed chords and slash chords first and even with just these beginning chapters my playing is taking on new naunces i recommend this book for anyone who is searching for new chords or sounds or who just wants to be able to play with more confdence and variety
