    • A musical piece correction apparatus corrects a sounding timing (note-on timings) of a sound constituting apart of a musical piece. First, the musical piece correction apparatus reads, from storage means, music performance data indicating sounding timings in the musical piece. Next, the musical piece correction apparatus sets a plurality of reference timings (grids) in a performance period of the musical piece, and sets, for each reference timing, a reference period (area) including said each reference timing. At this point, from among sounding timings included in the reference period, a nearest sounding timing to said each reference timing is selected, and the selected sounding timing is corrected so as to coincide with said each reference timing.
    • 音乐作品校正装置校正构成音乐作品的声音的声音定时(音符时刻)。 首先,音乐作品校正装置从存储装置读取表示音乐作品中的声音定时的音乐演奏数据。 接下来,乐曲校正装置在乐曲的演奏期间设定多个基准定时(网格),并且对于每个基准定时,设定包括所述每个基准定时的基准周期(区域)。 此时,从包括在基准期间的探测定时中,选择与所述各基准定时相对应的最近的探测定时,对所选择的探测定时进行校正,使其与所述各参考定时一致。
