John Weeks Moore, Complete Encyclopaedia of Music… (1880)
“ The chief excellence of that measured strain of music called air resides in the beauty of its melody, the symmetry of which lays hold of our affections in a peculiar way. When addressed to the gentler passions, its tender expressions are more intelligible than words, of which few are necessary to assist its meaning ; and the less it is encumbered with them, the more powerful is its charm. ”
