Felix Mendelssohn, Selected letters of Mendelssohn (1894)
“ She has the gift of composing songs and then singing them in a way I have never heard the like of; it is the most complete musical delight that ever yet fell to my lot. When she sits down at the piano and begins one of these songs of hers, the notes acquire a strange, new tone; all the music seems wonderfully swayed hither and thither, and in every note there is the finest and profoundest feeling. Then, when she sings the first bar in her tender voice, every hearer grows perfectly still and wrapt, and each in his own fashion feels himself penetrated through and through. ”
