The original print of this book uses Helmholtz pitch notation, where middle-C is represented by a lowercase c with one over-line, the C above with two over-lines, etc. For accessibility, I have used the alternative convention of using numbers after the note name, thus:
C₁ ... C ... c d e f g a b c¹ d¹ e¹ f¹ g¹ a¹ b¹ c² ... c³ ... c⁴
(C₁ = 3 octaves below middle-C, c⁴ = 3 octaves above middle-C)
A few corrections have been made to spelling and punctuation. A list of these amendments can be found at the end of the text.

Entered, according to Act of Congress, in the year 1872, by J. B. LIPPINCOTT & CO., In the Office of the Librarian of Congress at Washington.
The translator of this book, desirous, in common with other friends of its author, that her claims as a lady of rare scientific attainments should be recognized in this country, where she has recently taken up her abode, has obtained her consent to the publication of the following testimonials to her position in her own country from gentlemen of the highest eminence in science:
Mad. Emma Seiler has dwelt for a long time here in Heidelberg, and given instruction in singing. She has won the reputation of a very careful, skilled and learned teacher, possessing a fine ear and cultivated taste. While engaged on my book, “Die Lehre von den Tonempfindungen, &c.,” I had the honor of becoming acquainted with Mad. Seiler, and of being assisted by her in my essay upon the formation of the vowel tones and the registers of the female voice. I have 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.
I have pleasure in bearing this testimony to her worth, in the hope of securing for her the confidence and the encouragement of those who are interested in the scientific culture of music, and who know how desirable it is that an instructress in the art of singing should be possessed of scientific knowledge, a fine ear, and a cultivated taste.
