Abstract

The apparatus stores a data base including a plurality of sets of composition parameter data for a plurality of numbers of measures, each set of composition parameter data defining characteristics of a music piece to be composed, the characteristics including music structures, and at least one set of composition parameter data being provided for each number of measures among the plurality of numbers of measures. The user inputs composition conditions such as a length of time, a tempo and a meter for a music piece to be composed. The apparatus calculates the number of measures of the music piece based on the inputted time length, tempo and meter. A plurality of candidate data sets of composition parameters are searched for in the data base and displayed for the user's selection. The user selects a desired one, and the apparatus generates a melody satisfying the inputted composition conditions. When there may be a disparity between the time length of the generated melody and the time length in the inputted composition conditions, the tempo of the generated melody may be adjusted such that the both lengths become equal.
