Brand new to jazz and look forward to applying any new skills. I'm learning some basic jazz chords at this point, cool but everywhere I look it seems an absolute must to purchase "The Real Book". Thoughts? I can't 'read' music, I'm a tablature guy. Perhaps reading the chords I see in the book, figure the chord and apply it to songs I am or can become familiar with it can work. If anyone can help with learning some basic jazz ( a site, a book) it would be appreciated. Again, Should I purchase The Real Book?
