Abstract

A difficulty of each of change patterns of neck buttons R, G, and B is indicated by a change point, which is stored in association with the change pattern. Using this data, the change level of an operation pattern of the neck buttons in operation sequence data is digitized. The digitized change level of the operation pattern is displayed on a song selection screen as a feature of each operation sequence data. Such an absolute index indicating a feature of the operation sequence data enables a player to rely on the displayed index, which facilitates the player to select operation sequence data suitable for the player's skill or taste.
