Children's Perception of Motion in Unidirectional, Two- and Three-Pitch Melodic Patterns and the Related Effects of Change in Timbre, Loudness, and Duration.
Williams, David Brian
Three experiments examined the effects of selected factors of interval size, timbre, loudness, and length of the melodic pattern on children's ability to perceive, the motion of 2- and 3-pitch melodic patterns. Subjects for all experiments were 32 second- and 32 fifth-grade children. The task for each experiment consisted of identifying the motion of unidirectional 2- and 3-pitch melodic patterns which used melodic intervals of varying size. After each pattern, the child made a three-choice button push to indicate whether the music moved up, down, or to the same pitch. Experiment I trained children to focus on the pitch dimension of melodic motion. Experiment II examined the effect of varying the timbre and loudness of the first tone of the pattern. Experiment III examined the effect of increasing the length of the melodic pattern from 2 to 3 tones. The results indicated that errors in identifying melodic motion increased as melodic interval size became smaller. Timbre or loudness variations significantly biased perception of melodic motion in an ascending direction with the smallest melodic interval. No interaction was found between interval size and the variables of task and grades. Fifth graders performed significantly better than second graders. The results also indicated that the varied task was more difficult than the fixed task. (Author/BD)
