well. For this latter purpose a pronouncing index has been appended.
It is impossible to give credit to all sources from which ideas have been drawn, but especial mention should be made of the eminently clear and beautifully worded definitions compiled by Professor Waldo S. Pratt for the Century Dictionary, and the exceedingly valuable articles on an almost all-inclusive range of topics found in the new edition of Grove's Dictionary. Especial thanks for valuable suggestions as to the arrangement of the material, etc., are also due to Dr. Raymond H. Stetson, Professor of Psychology, Oberlin College; Arthur E. Heacox, Professor of Theory, Oberlin Conservatory of Music; and Charles I. Rice, Supervisor of Music, Worcester, Mass., as well as to various members of the Music Teachers' National Association who have offered valuable advice along certain specific lines.
