Abstract

La présente invention concerne un dispositif et un procédé d'affichage, ainsi qu'un programme permettant d'afficher avec précision des opérations de scratch. À cette fin, un dispositif d'affichage de la présente invention comporte une unité d'affichage qui présente une zone d'affichage en forme de disque et un contrôleur d'affichage qui fixe l'affichage d'une image de position de lecture destinée à indiquer les positions lues d'un morceau de musique à un angle décalé de N degrés (étant entendu que 0 ≤ N < 360) par rapport à la position de 0°, lorsque le bord inférieur de la zone d'affichage est réglé sur 0°, et fait pivoter l'affichage le long de la circonférence afin d'afficher l'image de position de battement indiquant chaque position de battement lorsque le nombre spécifié de battements dans un morceau de musique est représenté par des divisions égales lors d'un tour dans une direction circonférentielle, afin d'accompagner la lecture du morceau de musique dans la zone d'affichage.
