Thank you very much John for your details on this. My intent of course was not to say that film music analyses are only to be addressed to those who know music. It's just that academic musicological analyses of film scores don't exist (except for a couple of examples) and I believe people like me who have studied music for a lot of years, would be anxious to read such books for educational reasons (details about the construction of themes, the musical connection between them, the tonalities used and what they do represent, if there is a tonal plan and what does it want to show etc.) Aspiring to be a film composer, I really would love to read more books on this subject that would help me understand more.. that doesn't mean of course that I discard any other effort that is not addressed to musicians..
