Harry Collins Deacon, A Dictionary of Music and Musicians (1900)
“ The bare fact that the voice is produced in the larynx is ascertainable by anybody through the medium of the laryngoscope, but to arrive only thus far the throat has to be forced into a position directly antagonistic to the production of those very qualities of tone that form the subject of desired investigation. Open chest voice, there is every reason to believe, is in great part produced by the drawing down of the larynx by means of the sterno-thyroid muscles, so that it becomes part of a compact mass of bone, tissue, and cartilage all vibrating together. ”
