The object of this research is to ascertain some of the elements in the acquisition of accuracy of pitch in singing. The study was divided into three divisions; (1) a preliminary series of five tests, in which no information was given the observer in regard to the accuracy of his singing; (2) a practice series of ten tests, during which the observer was informed of the error in pitch after each trial; and (3) a final series of five tests conducted in the same manner as the first. The object of the first test was to ascertain the accuracy of their singing without training; the second was the training series, the object of which was to correct the errors and to form new tonal concepts and voluntary control; and the object of the third series was to find out whether or not the observers had profited by the training in the second series and to what extent they carried it over into actual practice
