Clue 4 hint 10

Using

http://en.wikipedia.org/wiki/Genetic_code#RNA_codon_table

I get "DEACCLIMATE".

Using the RNA codon table at http://en.wikipedia.org/wiki/Genetic_code#RNA_codon_table for Cytidine, Uridine, Adenosine, and Guanosine, and treating Cello notes G, A, C in the obvious way with the quarter rest symbol as U, you get a set of 11 RNA triples (one per measure) that decode to the word:

DEACCLIMATE
