Walter Parratt,
A Dictionary of Music and Musicians
(1900)
“ The very fact that the pianoforte is at its best unable to sustain tone equably, renders the acquirement of a 'singing' touch at once the more arduous and the more necessary, and this was recognised and insisted upon by Emanuel Bach. For an expressive melody to be hammered out with unsympathetic fingers of steel is far worse than for a passage to lose somewhat of its sparkle through lack of percussion. ”
