The purpose of this study was to determine the effects of prenatal music experiences, specifically a single music timbre, on one-week old infants' discrimination of a timbre heard prenatally and timbres not heard prenatally. Music timbres included in this study were alto voice, clarinet, trumpet, and violin. The researcher used fundamental frequencies between 261.63 Hz and 523.25 Hz and the aforementioned music timbres during prenatal and postnatal experiences to determine infant timbre discrimination. The primary research question was as follows. Can one-week-old infants discriminate between a music timbre heard prenatally and music timbres not heard prenatally? Discrimination was measured by changes in infant heart rate. Based on previous prenatal research, the assumption was that infant heart rate would decrease when infants recognized the timbre that was heard prenatally.Subjects--Topical Terms:

520 $a The purpose of this study was to determine the effects of prenatal music experiences, specifically a single music timbre, on one-week old infants' discrimination of a timbre heard prenatally and timbres not heard prenatally. Music timbres included in this study were alto voice, clarinet, trumpet, and violin. The researcher used fundamental frequencies between 261.63 Hz and 523.25 Hz and the aforementioned music timbres during prenatal and postnatal experiences to determine infant timbre discrimination. The primary research question was as follows. Can one-week-old infants discriminate between a music timbre heard prenatally and music timbres not heard prenatally? Discrimination was measured by changes in infant heart rate. Based on previous prenatal research, the assumption was that infant heart rate would decrease when infants recognized the timbre that was heard prenatally.
520 $a There were five groups of infants in this study. Four groups of infants were exposed prenatally to one of the aforementioned music timbre stimuli and served as the experimental group (<italic>n</italic> =14). One group of infants with no prenatal exposure to the music timbre stimuli served as the control group (<italic>n</italic> =12). Additionally, effects of other variables on infant timbre discrimination were examined, including the number of hours of exposure to the music timbre stimulus, other music exposure during the third trimester, Apgar scores at 1 and 5 minutes, gestational age at the week of delivery, birth weight, gender, age of infant when tested, and presentation order of the music timbres.
520 $a Seven of the fourteen infants in the experimental music timbre groups were able to discriminate between their prenatal music timbre and the timbres not heard prenatally. Of the 14 infants in the experimental group, 57% responded to the alto voice timbre, as measured by a decline in heart rate means. Approximately 50% of the infants in the experimental group responded to both the violin and trumpet timbres, as measured by a decline in heart rate means. Only 28% responded to the clarinet timbre, as measured by a decline in heart rate means. Of the 12 infants in the control group, 75% responded to both the alto voice and clarinet timbres, as measured by a decline in heart rate means. Forty-two percent of the control group infants responded to the violin timbre, and 33% responded to the trumpet timbre, as measured by a decline in heart rate means.
