John Weeks Moore, Complete Encyclopaedia of Music… (1880)
“ A musical string is of a uniform thickness, and is stretched between two points, by a force much greater than its weight. The stretching force which is applied is generally conceived as measured by the weight which would occasion an equal tension. The sound which a string gives, thus stretched, or in this mode of vibration, is called its fundamental sound. The tone of a string becomes more acute as we increase its tension, or diminish its length, and the weight of a given portion. ”
