In this paper, we apply a chord progression learning model to a rule-based generation of a four-part chorus. The proposed system is given a 32-note melody line and completes the four-part chorus based on the rule of harmonics, predicting the chord progression with the CRBM model. The data for the training model was collected from various harmony textbooks, and chord progressions were extracted with key-independent features so as to utilize the given data effectively. It was shown that the output piece obtained with the proposed learning model had a more natural progression than the piece that used only the rule-based approach.

This study analysed motion graphic formative image composition of TV LED backdrop to be used as background display for performers such as singers appeared on TV music show. Motion graphic LED images are comprised of various plane figures, and backdrop's design function as background screen has a goal to convey synesthesia and sensibility of visual elements. And this analyse classified sensibility concept about color, motion direction and speed to be elements of transmitting sensibility. As the analyse of graphic form among transmitting sensibility elements, this classified form type into its' applied elements, and studied how these elements' motion pattern and arrangement could be placed and replaced at song's four step composition, intro, verse, bridge, chorus part, and also characterized differences of backdrop design for male and female performers. As a case study, it included terrestial broadcasting TV song ranking shows targeted at teenagers. Because they carried out various motion design utilizations. Finally, this reasoned out mainly designing form type, its' applied elements, motion pattern and its' arrangements type division according to the song developing four steps.
