THE BRAIN AND THE VOICE IN SPEECH AND SONG

PREFACE
The contents of this little book formed the subject of three lectures
delivered at the Royal Institution "On the Mechanism of the Human Voice"
and three London University lectures at King's College on "The Brain in
relation to Speech and Song." I have endeavoured to place this subject
before my readers in as simple language as scientific accuracy and
requirements permit. Where I have been obliged to use technical anatomical
and physiological terms I have either explained their meaning in the text,
aided by diagrams and figures, or I have given in brackets the English
equivalents of the terms used.
I trust my attempt to give a sketch of the mechanism of the human voice,
and how it is produced in speech and song, may prove of interest to the
general public, and I even hope that teachers of voice production may find
some of the pages dealing with the brain mechanism not unworthy of their
attention.
