There are many music systems available on the market, such as systems for the automatic arrangement of music pieces given as note sequences for solo pianos into a piano score in a specific style. These systems, however, are usually designed to generate music by concatenation of existing arrangement patterns, so no one can expect that these systems will satisfy user requirements. We propose a system in which a given melody expressed as a note sequence is arranged into a modem Jazz-style score for the piano on the basis of the "Jazz theory," a theory of harmony used in Jazz and popular music. The performance of the proposed system is evaluated by comparing the results obtained with the proposed system with those obtained using popular arrangement systems available on the market. Experimental results show that arrangement using the proposed system is significantly superior to arrangement using systems available on the market.
