[TRANSLATED]
Mad. E. Seiler has made for herself an honorable name in Germany,
not only as a practical teacher of singing, but also by her
valuable investigations in regard to the culture of the musical
voice. By her own anatomical studies she has acquired a thorough
knowledge of the vocal organs, and by means of the laryngoscope has
advanced, in the way first trodden by Garcia, to the establishment
of the conditions of the formation of the voice. We owe to her
a more exact knowledge of the position of the larynx, and of its
parts in the production of the several registers of the human
voice; and she appears especially to have brought to a final and
satisfactory decision the much-vexed question respecting the
formation of the so-called _fistel tones_ (head tones). She has
been associated with the best powers possessed by Germany in the
department of the theory of music and physiological acoustics,
standing by the side of the celebrated physiologist, Helmholtz,
while he was engaged in his physiologico-acoustic work upon the
generation of the vowels and the nature of harmony.
