This paper proposes an automatic music composition method based on music theory for people who don't have musical knowledge or composing skill. Proposed method describes music by combination of “pieces". A piece expresses a musical measure. Firstly, user choices a music impression from some options. This impression decides the key of composed music. Secondly, base tones of pieces are decided from the tones consisting of the key by music theory. Thirdly, rhythm is selected from rhythm group at random. Fourthly, our method also decides tone row in every piece based on the base tone by music theory. Finally, the tone row links up with the rhythm to represent a melody. Our method uses tree structure to decide both of base tones and tone rows of pieces. The path with the maximum evaluation value shows the sequence of base tones and tone rows. We evaluated our method by a questionnaire survey about composed music.
