As shown in FIG. 3, the header information stores the total number of measures, the number of measures per line, paper sizes such as A4 and B5, measure information, pointer (address) information of each part information, and the like. In addition, information such as the number of parts, sound part information for each part, and pitch (interval between parts) is also included. Each part information stores a part name, a vertical position (relative position in a vertical direction from a reference point of a line) information, and note information for each bar.
Information such as key is also included.

The bar information stores information for each bar common to each part, and includes width data, linked data, beat data, and the like. The width data includes a 1-bit width change flag (ON = 1) and 7-bit width ratio data. The width ratio data takes a value of, for example, 0 to 100%. This width ratio data is as follows: W is the print width of one line corresponding to the paper size, N is the number of measures in one line, and M is the print measure width corresponding to the maximum display width in the display screen displayed one measure at a time.
It is represented by {W / (N × M)} × 100. The linked data indicates the linked state before and after the bar at the time of printing by, for example, data F and B of 4 bits each, whereby it is possible to determine whether the bar is the head, middle, or end of a line, for example. . In the screen display, a clef is displayed in the first measure and a staff is displayed in the middle measure beyond the vertical line of the delimiter in the middle measure according to the linked data. With such a display, the position of the bar at the time of printing can be easily recognized. The beat data is, for example, time information such as 4/4.
