[LISTEN]; the Thin, between
[LISTEN]; and the Small, above
[LISTEN]. The distinguishing features of these are so very clear as to make any mistake impossible. But now we come to sub-divisions, and with regard to these the matter is not so simple. Singers know very well that other breaks occur in the human voice besides those hitherto mentioned, and the question arises how they are to be accounted for by corresponding changes in the vocal organ. The evidence furnished on this point by the laryngoscope is, in my opinion, not sufficient, because the alterations in the vocal ligaments are so exceedingly minute as to be capable of being differently interpreted by different observers. I have consequently come to the conclusion that they cannot be accepted as indicating changes of mechanism unless corroborated and amplified by other signs.
In order to place the whole subject before the reader in a comprehensive form, I cannot do better than quote the elaborate description which Madame Emma Seiler gives of the registers in "The Human Voice in Singing" (Philadelphia, 1875). Madame Seiler, to whom Mr. Lunn is pleased to refer, on p. 65 of his treatise, as an "ignorant person," assisted Professor Helmholtz, of Heidelberg, in his essay upon the Formation of the Vowel-tones and the Registers of the Female Voice. He says he thus had "an opportunity of knowing the delicacy of her musical ear, and her ability to master the more difficult and abstract parts of the theory of music." The Professor further speaks of her as "a very careful, skilled, and learned teacher." Professor Du Bois-Reymond, of Berlin, also describes her as "a lady of truly remarkable attainments." With such recommendations I make no apology for quoting at length from Madame Seiler's writings; and it will be readily understood that whenever I differ from her, I do so with some diffidence, and only after careful conviction of the accuracy of my own independent observations.
I shall substitute the terms hitherto used in these pages for others employed by Madame Seiler, and I have added a diagram of the registers, which may assist the reader in forming a clear idea of the subject.
