Apparatus for analyzing music data and displaying music score

An apparatus for analyzing music data comprising:

• a time point data acquiring device for acquiring time point data contained in music data which represents a rhythmic progression of note events constituting a musical performance;
• an event time judging device for judging whether each of the respective event times represented by said time point data acquired by said time point data acquiring device comes within which of time windows as provided for a regular pattern rhythm category and for a tuplet rhythm category;
• a time event counting device for cumulatively counting the number of event times which come within the time windows for each of said rhythm categories, category by category, throughout the entire length of said musical performance;
• and
• a rhythm tendency judging device for judging whether said musical performance is in a tuplet-shy rhythm or in a tuplet-rich rhythm based on the number of event times as cumulatively counted with respect to each of said rhythm categories.

A computer readable medium containing program instructions executable by a computer for causing said computer to execute:

• a process of analyzing music data which represents a musical performance including a rhythmic progression of note events;
• a process of judging whether said music performance is in a tuplet-shy rhythm or in a tuplet-rich rhythm;
• a process of generating rhythm judgment information which represents said judgment result;
• a process of detecting note events which come at time points to be a tuplet from among said note events;
• a process of deciding a notation form of said note events based on said detected time points and with reference to the judgment by said rhythm analyzing device, said notation form being whether in a regular rhythm pattern form or in a tuplet form;
• and
• a process of displaying said note events in said decided notation form on a music score.
