For each one note or for each plurality of notes constituting a reference tone, a segment setting section (42) segments a time series of actual pitches of the reference tone into one or more note segments. For each of the one or more note segments, a relativization section (44) creates a time series of relative pitches that are relative values of individual ones of the actual pitches of the reference tone to a normal pitch of the note of the note segment. Information registration section (38) stores, into a storage device (14), relative pitch information comprising the time series of relative pitches of each individual one of the note segments. The segment setting section (42) may use musical score data, time-serially designating the notes of the reference tone, to set each of the note segments for each note designated by the musical score data, and may correct at least one of start and end points of each of the set note segments in response to user's operation. |
