This study is an experimental investigation of two groups of junior high school students in an effort to evaluate the advantages of workbooks in their music classes. The comparison was made with two classes composed of thirty-two students each from the two junior high schools in the Beaumont Independent School District. One class used the workbooks in conjunction with the regular singing and appreciation work, but the other class did not use formal workbooks. They discussed the theory and notation of the music in relation to the work they were doing.
