Vague Client Feedback
One of the most annoying things when scoring a film is getting inconclusive and vague feedback from your client. If you are not sure why your customer doesn’t like a particular cue even after he/she has given feedback on it, keep asking questions.
There is no point in doing several rewrites from guessing which is also something you might want to communicate to your customer. If you don’t find a common base to communicate on (maybe due to the director not being able to formulate anything musically), try to work with compareable scenes and cues – things like “Do you want it more like that scene from movie X?” might help to narrow down what is wanted.
Never let yourself being left by your client with just a “No, that’s not it. Try something new!”. First of all that is unprofessional and secondly it disrespects your work.
