The problem of absolute or positive pitch has been studied by a considerable number of researchers. This cannot be said, however, for the problem of the element of tempo, or the normal speed of the true beat in music. The reason for this probably lies in the fact that absolute pitch can be measured quite accurately, for it is dependent upon the anatomy and physiology of the ear. On the other hand, a means whereby the innate pulse in music can be externalized so as to be capable of exact expression and measure in number, presents a challenge to those interested in further investigation of this phenomenon.
