The Essays of Adam Smith
“ Even in the performance of the most humble of all artists, of the man who drums upon the table with his fingers, we may sometimes distinguish the measure, and perhaps a little of the humour, of some favourite song; and we must allow that even he makes some sort of Music. Without a proper step and motion, the observation of tune alone will not make a Dance; time alone, without tune, will make some sort of Music.That exact observation of tune, or of the proper intervals of gravity and acuteness, which constitutes the great beauty of all perfect Music, constitutes likewise its great difficulty. ”
