Hi guys, Sorry if this had been asked before. I want suggestions for everything(books, dvd's, etc), that can help me understand songwriting. I can understand a little of theory, like scales, chords and intervals, but I'm lost when I have to apply the theory that I know, to play and create music.. Like, I play a chord progression of 3 chords, but where I go after that? How to pick a melody line, and harmonize that line to maintain the melody(like jazz players do), and go after that so something different. I like jazz, progressive rock, so I need something that goes beyond the 1-4-5 progression. If possible, documents that are explained simple and concise. Thanks.
