If any sound depends on its place in what is technically called a 'scale,' the same sound producing absolutely difficult effects in the lar according as it is heard in connection with one or another series of sounds.

It is on this relative association of the sounds that all the essentially characteristic effects which are summed up in the phrase 'musical expression,' depend. But why certain associations of sounds have such & such effects is a problem which yet remains to be solved. These effects must, of course indeed, in some way or other, be connected with the well known arithmetical relations between the rates of vibration of the sounds forming a musical scale, & it is perhaps possible—but this is merely a suggestion that the greater or less mechanical facility with which the vibrating apparatus of the human larynx passes from one state of vibration to
