Abstract: A performance-information processing apparatus processes performance information entered thereto. When the performance information is entered in a time interval between (i) a starting time point, at which performance information of one note starts entering and (ii) a first timing, that is a certain time after another performance information of a note has been entered after the performance information of said one note was entered, a tempo determining unit determines a tempo of the performance information, based on the performance information entered in the time interval, and a meter determining unit which determines a meter of the performance information based on the tempo determined by the tempo determining unit.

Abstract: An automatic key adjusting apparatus is provided, which determines keys on an input melody in real time and adjusts the determined keys in non real time to obtain accurate keys, thereby enhancing accuracy of placement of chords. The automatic key adjusting apparatus is provided with a keyboard for playing a melody of a musical piece. CPU judges keys on the melody in real time based on a history of pitches of the played melody of the musical piece, and adjusts the result of the key judgment in non real time after the melody of the musical piece is played.
