Hola, alquien me podria decir el singnificado en este contexto? gracias
... eloquent, swelling wind chords and a figure in the violins that trickles gently down.

 

It's a figurative use - something like "destilar poco a poco"

 

en el contexto podria ser algo como ir desapareciendo poco a poco?

 

The sense is more bajando than desapareciendo I think. The sound might not stop entirely - but, if you have more context that suggests it does stop, then desapareciendo seems fine.

 

gracias por la ayuda
