SCORING A MUSICAL PERFORMANCE AFTER A PERIOD OF AMBIGUITY

Described are methods, systems, and apparatuses, including computer program products, for scoring a musical performance after a period of ambiguity in a rhythm-action game. This is accomplished by displaying a first target music data and a second target music data where the first target music data's tolerance threshold overlaps with a second target music data's tolerance threshold. When a music performance input data is received, the game platform determines if the music performance input data is within both tolerance thresholds. Then scores are determined, based on a degree of matching between the music performance input data and the first target music data and between the music performance input data and the second target music data. The game platform then assigns the music performance input data to whichever target music data has the higher score when the difference between the first and second scores is greater than a predetermined value.
