Note 443 — Chapter II
Francis Plumptre Beresford Osmaston translation
I am not sure there is not a certain confusion here. Our text, at any rate, when speaking of wind instruments, refers to the column of air as the medium of sound, but in the case of stringed instruments draws attention rather to the thing which creates the waves of vibration, the string itself. The nature of the timbre of an instrument is no doubt an important one, but it may be questioned whether this distinction between line or column and surface is very satisfactory or sufficient.
