Abstract

An electronic musical instrument including a musical instrument body which is supported by first finger of a hand of an instrument player and at least one finger other than the first finger, scale keys which are provided at positions that are contacted with fingers other than the first finger on one surface of the musical instrument body, and each of which specifies a scale of a musical sound, a touchpad which is provided in an area that is contacted with the first finger on an other surface of the musical instrument body, and includes a sensor that has a planar detection area for detecting a contact position of the first finger, and a processor which controls emission of the musical sound whose scale has been specified by the scale key in accordance with the contact position of the first finger detected by the touchpad.

First claim

What is claimed is:

1. An electronic musical instrument, comprising:
a musical instrument body which is supported by a first finger of a hand of an instrument player and at least one finger other than the first finger;
scale keys which are provided at positions that are contacted with fingers other than the first finger on an upper side of the musical instrument body during a musical performance, and each of which specifies a scale of a musical sound;
a touchpad which is provided in an area that is contacted with the first finger on a lower side of the musical instrument body during the musical performance, and which includes a sensor that has a planar detection area for detecting a contact position of the first finger; and
a processor which controls emission of a musical sound whose scale has been specified by a respective one of the scale keys in accordance with the contact position of the first finger detected by the touchpad,
wherein the touchpad detects an instruction operation performed in a specific direction based on a change in the contact position of the first finger in the planar detection area, the specific direction including at least one of a first direction along a longitudinal direction of the musical instrument body and a second direction perpendicular to the first direction.

2. The electronic musical instrument according to claim 1 , wherein the sensor of the touchpad having the planar detection area has a plurality of electrodes of touch sensors arrayed at least in the second direction along a lower surface of the musical instrument body.

3. The electronic musical instrument according to claim 1 , wherein the sensor of the touchpad having the planar detection area has a plurality of electrodes of touch sensors arrayed in the first direction and the second direction along a lower surface of the musical instrument body.

4. The electronic musical instrument according to claim 1 , wherein the touchpad detects a magnitude of a pressing force of the first finger applied in a third direction from the lower side of the musical instrument body toward the upper side thereof, the specific direction further including the third direction.

5. An electronic musical instrument, comprising:
a musical instrument body which is supported by a first finger of a hand of an instrument player and at least one finger other than the first finger;
scale keys which are provided at positions that are contacted with fingers other than the first finger on a first surface of the musical instrument body, and each of which specifies a scale of a musical sound;
a touchpad which is provided in an area that is contacted with the first finger on a second surface of the musical instrument body, and which includes a sensor that has a planar detection area for detecting a contact position of the first finger; and
a processor which controls emission of a musical sound whose scale has been specified by a respective one of the scale keys in accordance with the contact position of the first finger detected by the touchpad,
wherein the processor controls to provide a predetermined effect on the musical sound whose scale has been specified by the respective one of the scale keys, in accordance with an instruction operation detected by the touchpad.

6. The electronic musical instrument according to claim 5 , wherein the processor controls a polarity and an intensity of the effect that is provided on the musical sound, in accordance with the instruction operation detected by the touchpad.

7. The electronic musical instrument according to claim 5 , wherein the processor simultaneously or individually provides a plurality of different effects on the musical sound, in accordance with instruction operations simultaneously or individually detected by the touchpad.

8. The electronic musical instrument according to claim 5 , wherein the processor simultaneously or individually provides a plurality of different effects on the musical sound, in accordance with instruction operations performed by first fingers of hands of the instrument player and simultaneously or individually detected by the touchpad.

9. The electronic musical instrument according to claim 5 , further comprising:
a function setting section which arbitrarily sets effects to be provided on the musical sound, for each of instruction operations that are detected by the touchpad.

10. The electronic musical instrument according to claim 1 , wherein the planar detection area of the touchpad is provided at two positions including a position to be contacted with a first finger of a right hand of the instrument player and a position to be contacted with a first finger of a left hand of the instrument player on the lower side of the musical instrument body.

11. The electronic musical instrument according to claim 1 , wherein the electronic musical instrument is an electronic wind instrument, and
wherein the touchpad detects the contact position of the first finger in a lateral direction of the electronic wind instrument.

12. A control method for an electronic musical instrument having a musical instrument body which is supported by a first finger of a hand of an instrument player and at least one finger other than the first finger, the control method comprising:
determining a scale of a musical sound in accordance with an operation on a respective one of scale keys provided at positions that are contacted with fingers other than the first finger on an upper side of the musical instrument body during a musical performance;
detecting a contact position of the first finger in accordance with an operation on a touchpad which is provided in an area that is contacted with the first finger on a lower side of the musical instrument body during the musical performance, and which includes a sensor that has a planar detection area; and
controlling emission of the musical sound whose scale has been determined in accordance with the detected contact position of the first finger,
wherein the touchpad detects an instruction operation performed in a specific direction based on a change in the contact position of the first finger in the planar detection area, the specific direction including at least one of a first direction along a longitudinal direction of the musical instrument body and a second direction perpendicular to the first direction.

13. The control method according to claim 12 , wherein a magnitude of a pressing force of the first finger applied in a third direction from the lower side of the musical instrument body toward the upper side thereof is detected in accordance with the instruction operation on the touchpad, the specific direction further including the third direction.

14. A control method for an electronic musical instrument having a musical instrument body which is supported by a first finger of a hand of an instrument player and at least one finger other than the first finger, the control method comprising:
determining a scale of a musical sound in accordance with an operation on a respective one of scale keys provided at positions that are contacted with fingers other than the first finger on a first surface of the musical instrument body;
detecting a contact position of the first finger in accordance with an operation on a touchpad which is provided in an area that is contacted with the first finger on a second surface of the musical instrument body, and which includes a sensor that has a planar detection area; and
controlling emission of the musical sound in accordance with the detected contact position of the first finger,
wherein a predetermined effect is controlled to be provided on the musica
