Problem The primary purpose of this study is to attempt to isolate factors causing uncertain singing in the first grade, and to study what relationship, if any, exists between pitch discrimination and vocal reproduction of sounds, as measured by simple tests, devised for use in this study. The scope is limited to 121 first grade children, during one school year. II. the Research Procedure A study of the available data reveals that the causes of uncertain singing are generally grouped under four main categories. These are: 1) faulty pitch perception, 2) inability of the vocal apparatus to coordinate to a degree so as to reproduce this pitch, 3) Immaturity, and 4) lack of singing experience or insufficient musical background.
