Abstract

Provided is a program for musical performance which causes a computer of a musical performance apparatus to function as a posture variation acquisition unit 101 for acquiring the posture variation of a controller 5 per frame based on the angular velocity with respect to the posture or movement of the controller 5, a volume parameter setting unit 102 for setting a volume parameter for deciding the volume according to the posture variation, and a sound signal output unit 106 for outputting a sound signal of the volume according to the volume parameter.

Claims

1. A computer-readable non-transitory medium recorded with a program for musical performance which causes a computer of a musical performance apparatus for outputting sound based on movement of a predetermined target, to function as:

posture variation acquisition means for acquiring posture variation of the predetermined target in a predetermined interval based on measurement information concerning the posture or movement of the predetermined target;

volume parameter setting means for setting a volume parameter for deciding a volume according to the posture variation; and

sound signal output means for outputting a sound signal of the volume according to the volume parameter.

2. The computer-readable non-transitory medium recorded with a program for musical performance according to claim 1,

wherein the posture variation acquisition means acquires the posture variation as a result of the posture variation of the predetermined target being calculated in a predetermined interval relative to a coordinate system defined in a real space based on the measurement information.

3. The computer-readable non-transitory medium recorded with a program for musical performance according to claim 2,

wherein the posture variation acquisition means acquires a plurality of posture variations of the predetermined target relative to axes of the coordinate system defined in the real space, and

the volume parameter setting means sets the volume parameter based on two or more posture variations in descending order of value among the plurality of posture variations acquired by the posture variation acquisition means.

4. The computer-readable non-transitory medium recorded with a program for musical performance according to claim 3,

wherein the posture variation acquisition means acquires, four posture variations of two axes for defining the posture of the predetermined target relative to two axes in the coordinate system defined in the real space, for each combination of axes, and

wherein the volume parameter setting means sets the volume parameter based on two posture variations in descending order of value among the four posture variations acquired by the posture variation acquisition means.

5. The computer-readable non-transitory medium recorded with a program for musical performance according to claim 1,

wherein the posture variation acquisition means acquires, as the posture variation, an average value of the posture variations acquired a plurality of times within a predetermined period.

6. The computer-readable non-transitory medium recorded with a program for musical performance according to claim 1, which causes the computer to further function as:

output volume control means for stopping the output of the sound signal by the sound signal output means for a predetermined time or lowering the output volume of the sound signal by the sound signal output means when it is determined, based on the measurement information, that the positive and negative of angular acceleration in a predetermined direction have inverted.

7. The computer-readable non-transitory medium recorded with a program for musical performance according to claim 1,

wherein the volume parameter setting means sets the volume parameter based on information prescribing a correspondence of the posture variation and the volume parameter, and

in the information prescribing the correspondence of the posture variation and the volume parameter, tendency of inclination of change of the volume parameter relative to change of the posture variation differs for each range of the posture variation.

9. The computer-readable non-transitory medium recorded with a program for musical performance according to claim 1,

wherein the predetermined target is a controller with a built-in gyro sensor to be operated by a user, and

the measurement information is angular velocity or angular acceleration measured by the gyro sensor.

8. The computer-readable non-transitory medium recorded with a program for musical performance according to claim

wherein the musical performance apparatus simulates a stringed instrument having a plurality- of strings stretched in substantially the same direction, and

the program causes the computer to further function as:

string designation information retention means for retaining string designation information which designates a string that is currently a target to be sounded among the plurality of strings; and

string changing means for changing the string designated by the string designation information when it is determined, based on the measurement information that angular acceleration to a circumferential direction centering on a direction in which the plurality of strings are stretched has exceeded a predetermined threshold.

10. A musical performance apparatus for outputting sound based on movement of a predetermined target, comprising:

posture variation acquisition means for acquiring posture variation of the predetermined target in a predetermined interval based on measurement information concerning the posture or movement of the predetermined target;

volume parameter setting means for setting a volume parameter for deciding a volume according to the posture variation; and

sound signal output means for outputting a sound signal of the volume according to the volume parameter.

11. A musical performance system for outputting sound based on movement of a predetermined target, comprising:

posture variation acquisition means for acquiring posture variation of the predetermined target in a predetermined interval based on measurement information concerning the posture or movement of the predetermined target;

volume parameter setting means for setting a volume parameter for deciding a volume according to the posture variation; and

sound signal output means for outputting a sound signal of the volume according to the volume parameter.

12. A musical performance method for causing a computer of a musical performance apparatus for outputting sound based on movement of a predetermined target to execute the steps of:

acquiring posture variation of the predetermined target in a predetermined interval based on measurement information concerning the posture or movement of the predetermined target;

setting a volume parameter for deciding a volume according to the posture variation; and

outputting a sound signal of the volume according to the volume parameter.
