Overview of the work
The expression does not raise questions to the musicians, especially to the percussionists, and indeed, today the statement: "On the double" refers to the idea of an immediate fulfillment of an order. However, the title of this book is not intended to refer to the most associated meaning to the term, but to renew the meaning of this phrase, recalling the importance that the percussion instruments have always had in the phenomena of human communication. In other words, "On the Double" We can organize groups of children with tremendous ease at the same time we have established a means of universal and effective communication, which ultimately contributes to the motivation of juveniles.
