Bravo, Diego!!! That is truly brilliant, and you deserve to be a member of the A team of worldwide arrangers. You have a very comprehensive and sophisticated harmonic language, and a very good instinct about the various colours of the orchestra and how to use them.Your woodwind passages are really beautiful.
If I had any useful comment to make it would be to remind you of two famous sayings, i.e. Count Basie said “ it’s what you leave out that counts’’. And “less is more”. It might be worth thinking about that, as it’s sometimes a good idea to write horizontally instead of vertically, so that, for instance, the inner parts of the string writing are in themselves melodic. A famous conductor once said that “the secret of music is how you get from one note to another”. One of the great artists of the 18th century said that the two arts closest to one another are music and architecture, meaning that both consist of solids and voids, and in the case of music meaning the difference between opaque and transparent. I hope this makes sense and may be useful.
Keep writing, Diego, and send me some more.
Best wishes,
Jeremy
