Thanks Larry for the reply. In addition to learning orchestral arranging, I am also learnng how to do mixing as well. It seems there is a separate skill needed for each stage of creation. Stage one is the initial idea (melody, harmony, development, etc). Next is the arrangement - choosing the instruments for each harmonic line. Then finally the mixdown. Stage one is usually relatively easy for me. For the arrangment - I seem to be getting better. As for mixing - I have a long way to go.
Your advice is very important to me and I will take that into consideration for my next piece.
Thank you so much
