Catharine Esther Beecher,
Common Sense Applied to Religion…
“ The operation of mere sound, disconnected with the ideas which are often conveyed by it, is a subject of curious speculation. Sounds differ from each other in quality, pitch, force, and in length. The difference in tone may be illustrated by the sounds of a clarionet compared with the sound of a bell or of the human voice. Every instrument and every human voice has each a peculiar tone by which it is distinguished from all others. The difference in pitch is shown by sounding a low and a high note in succession on an instrument. ”
