Research on the influence mechanism of digital music teaching platform on the development of students' rhythmic perception and musical creativity in preschool education

In order to improve preschool children's understanding of music, creativity of music and perception of music rhythm, this paper researches the application of digital music platform based on the teaching process of digital music teaching platform from the three dimensions of rhythm training, music creativity and interactive music games. The influence mechanism model is constructed through interactive learning and personalized feedback mechanism, and the optimization strategy of music teaching is realized based on online and offline mixed teaching strategy and the development of personalized teaching plan. The traditional teaching method was divided into the control group, and the digital music teaching platform was divided into the experimental group. In the improvisation ability and independent arrangement and expression ability, the scores of each index in the experimental group increased to more than 4 points. In the control group, students' scores increased to more than 2 points in each index. In rhythmic perception, the rhythmic imitation accuracy of students in the experimental group increased by 36.08%, rhythmic stability increased by 50%, and beat memory was widened by 5 beats, which was more outstanding compared with the control group. The music teaching accomplished through the digital music teaching platform can effectively improve preschool children's rhythmic perception and musical creativity.
