Tone synthesizing data generation apparatus and method

A pitch trajectory creation apparatus comprising:

• a storage device which, for each of a plurality of note segments corresponding to a plurality of nominal notes of different attributes, relative pitch information comprising a time series of relative pitches, the time series of relative pitches representing a time series of actual pitches of a reference tone in relative values to a normal pitch defined by a nominal note of the reference tone;
• and
• a trajectory creation section which selects, from the storage device, the relative pitch information corresponding to a designated note, modulates a normal pitch corresponding to the designated note in accordance with the time series of relative pitches included in the selected relative pitch information and thereby creates a pitch trajectory indicative of a time-varying pitch of the designated note.

A computer-implemented method for creating a pitch trajectory, said method comprising:

• a step of accessing a storage device storing therein, for each of a plurality of note segments corresponding to a plurality of nominal notes of different attributes, relative pitch information comprising a time series of relative pitches, the time series of relative pitches representing a time series of actual pitches of a reference tone in relative values to a normal pitch defined by a nominal note of the reference tone;
• a step of selecting, from the storage device, the relative pitch information corresponding to a designated note, in response to access to the storage device;
• a step of modulating a normal pitch corresponding to the designated note in accordance with the time series of relative pitches included in the selected relative pitch information and thereby creating a pitch trajectory indicative of a time-varying pitch of the designated note.

A computer-readable storage medium containing a group of instructions for causing a computer to perform a method for creating a pitch trajectory, said method comprising:

• a step of accessing a storage device storing therein, for each of a plurality of note segments corresponding to a plurality of nominal notes of different attributes, relative pitch information comprising a time series of relative pitches, the time series of relative pitches representing a time series of actual pitches of a reference tone in relative values to a normal pitch defined by a nominal note of the reference tone;
• a step of selecting, from the storage device, the relative pitch information corresponding to a designated note, in response to access to the storage device;
• a step of modulating a normal pitch corresponding to the designated note in accordance with the time series of relative pitches included in the selected relative pitch information and thereby creating a pitch trajectory indicative of a time-varying pitch of the designated note.
