Communicating With a Client
Don’t expect your director to have enough musical knowledge to be able to communicate in musical terms. Find a way to make communication with him/her clear when presenting your concept or ideas.
A good way is to talk in emotions like “It needs to be a bit more sad here” instead of “I think it needs lots of minor chords and an English Horn solo here.” It also a good plan to present examples of what you want to do, even if you’re not yet in the state of presenting demos. Find movies, scenes, music pieces which roughly illustrate what you have in mind and talk him/her through. The better you sell your concept in the meetings, the better the chances are to get through with it.
However always remain open for real critizism and other ideas.
