MusicFlow: An interactive music composition system Music notation has evolved to the point in which music scores can be digitalized to give composers a different dimension of music composition. Traditional method of music notation using pen and paper requires much time and effort especially during reviewing and editing of hand written music scores. On the other hand of the spectrum, computerizing the entire music composition process can potentially reduce the workload; however, previous approaches in digitizing music notation suffer from the overwhelming functions and the lack of human touch. In this paper, we designed, implemented, and evaluated a multitouch application called Musicflow, which allows for automatic transcription of composersu0027 music into digital music scores through oneu0027s fingertips. To facilitate natural, efficient interaction, MusicFlow supports many multitouch gestures such as music notation, editing and playing back for reviewing. In addition, Musicflow includes a collaborative teaching tool which further enhances music education by engaging both the teacher and students actively on a multitouch table. Our initial evaluation indicates that MusicFlow is intuitive to use and effective for music composition.

Visual Education of Music Course for College Students Based on HumanComputer Interaction Visual education is an emerging education method in many Chinese colleges. However, the visual education in Chinese colleges has not attached enough importance to the handson ability and comprehension ability of college students. To solve the problems, this paper designs and applies a visual education method for music courses in colleges based on the humancomputer interaction system. Special attention was paid to the formulation of the humancomputer interaction system, which is essential for visualization of music information. Based on the masterslave mode, the humancomputer interaction system introduces the cloud control into the visual education of music. The proposed method was verified through the application in a university of Nanjing, China. The results show that our method greatly boosts the acquisition of music information by college students and effectively arouses their interests in music. The research results lay the basis for wider application of visual technology in education.
