Practicing a musical instrument alone can be both tedious and uneasy to reflect on. Spicing up the process and proving convenient access for reviewing will thus benefit music learners. Standing on a thorough disentangling of the development of CAMIT systems, we propose MelodyShop, a real-time audio-to-visual interactive system that translates music into fun images with comprehensible visual elements to indicate features of the performance and facilitates self-reflection by allowing users to visually adjust the drawings and thus make improvements on the music, so as to explore better performance as well as to establish reference for further practice. We prototyped to examine the feasibility of this novel interaction design.
