PROBLEM TO BE SOLVED: To make original chord data effectively utilizable for production of novel chord progress data and to support the production and edition work by presenting the original chord data constituting original chord progress data as candidates for the chord data constituting the fresh chord progress data to be newly produced and replacing a part of the automatically produced chord progress data with the original chord data. SOLUTION: A controller analyzes note data by applying musical knowledge, extracts the chord tones (candidates) in the note data, compares the resulted respective sections (4 measures, 2 measures and 1 measure) and the actual chord progress and determine the matching chord progress pattern as the chord progress (candidate) data. In succession, the controller displays the formed chord progress candidate data in a recommended chord group display region 47. The candidates having high priority among the chord progress data candidates are written into a chord memory and are displayed on the chord progress data display region (chord section) 46 and are transferred (supplied) to a code sequencer. |
