Friedrich Wieck,
Piano and song
“ Is it, then, so difficult to obtain the requisite knowledge of the human voice, and to study the scores of Gluck, Haydn, Mozart, Rossini, Bellini, and Donizetti with a special regard to this? Do our vocal composers make too great a sacrifice to their creative genius in making a study of those things which are essential? You consider it mortifying to inquire of those who understand singing, and you are sensitive about any disturbance of your vain over-estimate of your own powers; but you are not ashamed to cause the destruction of man's noblest gift,—the human voice! ”
