An analysis of content delivery systems using speaking voice, speaking with repetition voice, chanting voice, and singing voice
A random sample of 360 kindergarten students from the southeastern and the far western United States heard information about the solar system presented through four different vocal delivery styles: speaking alone, speaking with repetition, chanting, and singing. The singing and chanting group performed significantly higher than the speaking with repetition group and the speaking alone group (up = 0.00) on an eleven item test of factual information. The speaking and chanting groups were not significantly different from each other. There was no correlation with musical aptitude and gain on the pretest and posttest as measured by Edwin Gordon's Primary Measure of Music Audition .
