3. Modes of sounds.
The like variety have we in sounds. Every articulate word is a different modification of
sound; by which we see that, from the sense of hearing, by such modifications, the mind may be furnished with
distinct ideas, to almost an infinite number. Sounds also, besides the distinct cries of birds and beasts, are
modified by diversity of notes of different length put together, which make that complex idea called a tune, which
a musician may have in his mind when he hears or makes no sound at all, by reflecting on the ideas of those
sounds, so put together silently in his own fancy.
