Cinesamples release “Sonore” Trumpet & Horn Library
“Sonore (adj.): resonant; with rich tone. When you see “sonore” written in a musical score, the composer is simply asking the musicians to play with the maximum resonance, body and tone of which they are capable. It is the opposite concept of brashness and blasting – “sonore” is a thick and warm sound.”
