1. An automatic performance apparatus comprising:
- input means for inputting musical sound information of a musical piece which includes melodic musical sound information corresponding to a melody of said musical piece and chordal musical sound information corresponding to a chord to be added to the melody, in accordance with a progression of said musical piece;
storage means coupled to said input means and having, in a single memory area, a plurality of memory locations, each of said memory locations selectively storing said melodic sound information and said chordal musical sound information corresponding to a chord to be added to the melody, said melodic and chordal musical sound information being inputted by said input means, the storing order of the melodic musical sound information and of the chordal musical sound information in said plurality of memory locations being determined by the musical piece to be stored, said melodic musical sound information stored in a given memory location including at least note pitch code data and note length code data, and said chordal musical sound information stored in a given memory location including at least chord name code data and chord length code data;
reading means coupled to said storage means for successively and sequentially reading out the musical sound information stored in said memory locations of said storage means, said reading means including a single address designation means for sequentially designating addresses of memory locations in said single storage means from which said musical sound information is to be read out; and
musical sound producing means coupled to said reading means for producing musical sounds corresponding to the melody and chord based on the musical sound information successively read out by said reading means.

Abstract
An automatic performance apparatus includes input circuitry for serially inputting musical sound information of a predetermined melody and musical sound information to be imparted to the melody, in accordance with progressions of the melody and a chord. A storage device serially stores the musical sound information inputted, and readout circuitry successively reads out the musical sound information stored in the storage device. Accordingly, the musical sounds based on the read out musical sound information are reproduced, and a melody and a chord are played simultaneously.
