This Course consists of a graded series of six elementary Music Readers (thus giving new music for each grade) and a High School Reader, with accompanying Charts. Every device that would make the books useful has been adopted. The exercises and songs are well adapted to the different grades and are all of a high order. It is believed that this series is by far the most complete and useful one ever published in this country. _Whiting’s Public School Music Charts._ First Series, 30 charts, $6.00; Second Series, 14 charts, $3.00; charts separately (two charts on a leaf), 50 cents. The First Series is designed for the lowest primary grades, which should be taught from the charts before they read from the First Music Reader. The Second Series is designed for the lowest Grammar Grades, and should precede the use of the Second Music Reader. These Charts are well graded, progressive, educative, and interesting. _Whiting’s Complete Music Reader._ Boards. 224 pages. Price, 75 cents. Designed for Mixed, High, and Normal Schools, Academies, and Seminaries. A large variety of exercises and solfeggios are given for practice in connection with the Rudimentary Department, which is quite complete.
