My first plan was to take away entirely the present development of the Minor Keys; but, on consideration, it seems best to leave them exactly as they are, and to add fresh musical developments of the Minors, explaining them, and leaving it needless, for those who do not wish to look deeper into the subject, to examine the former development. Should they do so, however, they will see that not a single note is altered, the only difference being the Scales developing by fifths instead of by sevenths.
