In commencing a paper the writer frequently feels it a duty to begin with an apology for introducing such a subject. In the present case I feel that no apology whatever is needed, for to those interested in the teaching of music, the training of the ear of their pupils is a subject which is rapidly becoming one of the greatest importance. It is still in its infancy, but to the large number of conscientious teachers it is presenting itself with an ever-increasing force. We have been at great pains in England to secure that the rudiments of music shall be taught intelligently to the young pupil. Every scheme of examination in practical, as well as in theoretical, music has insisted on all candidates properly understanding the basis of the art. How greatly the musical perception and intelligence of the average pupil has improved by this means, anyone may see who will but compare a musical schoolgirl of twenty years ago with one of to-day.
