**Ramsay**

In getting the length of a string, in inches or otherwise, to produce the scale of music, any number may be fixed on for the unit; or for the vibrations of the root note any number may be fixed on for the *unit*; but in the *fractions* which show the *proportions of the notes of the scale*, there is no coming and going here; this belongs to the invariables; there is just one way of it. Whatever is not sense here is **nonsense**. It is here we are to look for the truth. The numbers which express the quantities and the numbers which express the motions are always related as being of the same kind. The fractions bring their characters with them, and we know by this where they come from. 1/4 of a string gives a note 2 octaves above the whole string, no matter what may be its length; 2 has exactly the same character as 1; 2/4 gives the note which is 1 octave above the whole string; but in the case of 3/4 here is a new ingredient, 3; 3/4 of a string gives a note which is a *fifth* below the [Scientific Basis and Build of Music, page 75]
