Abstract:
1. A tone data processing apparatus comprising: a storage section storing therein tone data sets, each representative of a plurality of sounds in a predetermined time period, and tone rhythm patterns, each representative of a series of sound generation times of the plurality of sounds, in association with each other; a notification section which not only causes designated times in the time period to progress in accordance with passage of time but also notifies a user of the designated times; an acquisition section which, on the basis of operation input by a user while the designated times are being notified by said notification section, acquires an input rhythm pattern representative of a series of the designated times corresponding to a pattern of the operation input by the user; and a search section which searches the tone data sets stored in said storage section for a tone data set associated with a tone rhythm pattern whose degree of similarity to the input rhythm pattern satisfies a predetermined condition, wherein said storage section stores therein categories of rhythms, determined on the basis of the sound generation time intervals represented by the tone rhythm patterns, in association with the tone rhythm patterns, wherein said tone data processing apparatus further comprises: a determination section which, on the basis of intervals between the designated times represented by the input rhythm pattern, determines a category of rhythm the input rhythm pattern belongs to; and a calculation section which calculates a distance between the input rhythm pattern and each of the tone rhythm patterns, and wherein said search section calculates a degree of similarity between the input rhythm pattern and each of the tone rhythm patterns on the basis of relationship between the category of rhythm the input rhythm pattern belongs to and a category of rhythm the tone rhythm pattern belongs to, and the tone data set identified by said search section is a tone data set associated with a tone rhythm pattern of which the degree of similarity to the input rhythm pattern, calculated by said search section, satisfies a predetermined condition.
