RUDIMENTS OF MUSIC is intended for all beginners in music theory. It is written to be useful (1) for introductory instruction as early as the secondary school level, (2) for college-level nonmusic majors, (3) for music majors needing a comprehensive review, or (4) for individuals or groups desiring to gain music literacy and thereby enhancing their enjoyment of music. The traditional elements of music are covered: notation, pitch, time and time signatures, the keyboard, scales and key signatures, closing with an elementary presentation of chords and their progressions. The subject matter is presented in small increments, each followed immediately by an exercise. This textbook/workbook format allows for quick reference while the student completes the exercise, and, for many of the exercises, immediate feedback on completion by referring to the Answer section, found as Appendix E This procedure is effective when used either as a classroom activity or as an assignment to be used outside the classroom. Other features of the book include (1) Appendices A-E with supplementary materials effective in correlation with the text, but not readily available elsewhere; (2) abundant illustrations, including many music excerpts by well-known composers; and (3) the inclusion with each volume of a cardboard keyboard that may be slipped behind an actual keyboard, or used atop a flat surface when an actual keyboard in not available. Its reverse side displays a Glossary of the basic subject matters presented in the text.Robert W. Ottman is the author of 'Rudiments of Music (4th Edition)', published 2003 under ISBN 9780131826557 and ISBN 0131826557.
