ABSTRACT:
Performance data is comprised of a successive serial arrangement of note data formed with paired pitch data and note duration data and of rest data formed with only rest duration data and having no pitch data. A performance data processing apparatus judges whether a rest datum following a note datum is shorter than a predetermined duration, and in case the result of this judgment if YES, the apparatus integrates the rest datum and the note datum preceding the rest datum into an integrated note datum having a note pitch of the note datum and a note duration which is equal to the sum of the duration of the note datum and the duration of the rest datum, whereby, in case a music score is displayed or printed out based on the performance data, rests having a duration shorter than the predetermined duration are eliminated to prolong the duration of the respective preceding notes each by an amount of the duration of the eliminated rest. Thus, there is obtained a music score having inscriptions similar to those of an ordinary music score, and also there can be reproduced a performance which is free of an unnatural sense.
