The interactive music education in cloud computing environment is designed to address the disadvantages of traditional music instructional mode. The content of interactive music education is investigated using cloud computing technology. The database of interactive teaching automation grouping platform is generated based on the basic learning information of learners in the data, and it is used to provide instructional resources and basic technical support.
