The overall purpose of this study was the investigation of the singing abilities of kindergarten and first grade children. Information was sought concerning the following: (1) the maximum singing range of preschool children compared to that of first grade children, (2) the range within which accurate singing could be expected from the majority of kindergarten and first grade children, (3) the relative ease with which most children hear and vocally reproduce comparable major and minor melodies, and (4) the developmental stages in musical growth evidenced by kindergarten and first grade children. Related research is reviewed. The present study was conducted in two cities. The criterion test, administered as a game, was given individually to each child. Each item of the test was played on a sing bell by the examiner, then sung by the examiner. The examiner then asked the child to sing the item. The entire test was recorded on magnetic tape for later evaluation. Results include: (1) The child in this stage of development habitually uses his speaking voice instead of his singing voice; (2) The child will normally sing in a vocal quality, but will not consistently perform the correct melodic direction; (3) There are two types of singers: the one who sings at the proper pitch level but evidences intonation problems, and the one who transposes the entire melody to another key; and (4) The child will sing most of the melody accurately. It is concluded that girls possess lower pitched voices than boys and blacks lower than whites and that white children have a wider singing range than comparable black children. (CK)
