Description

  The present invention relates to an electronic musical instrument, and more particularly to an electronic musical instrument that generates a musical tone having a pitch corresponding to a continuous movement of a performer.

  There is known an electronic musical instrument in which a musical tone having a pitch corresponding to the continuous movement of a performer is generated. An example of such an electronic musical instrument is theremin. When the movement of such an electronic musical instrument is slightly shifted, musical sounds having different pitches are output by the shift. For this reason, the performer requires skill to play such an electronic musical instrument and output a musical tone having a predetermined scale. For this reason, such an electronic musical instrument is desired to make the operation easier when outputting a musical sound of a predetermined scale.

  Utility Model Registration No. 3118541 discloses an intuitive and easy way for even the first person to use this instrument by converting the player's continuous movements and changes in physical quantities into pitches according to the scale. An electronic musical instrument that can be played is disclosed. The electronic musical instrument has a shape of a doll in which a human hand enters, and an electrical detection means capable of detecting a continuous change in physical quantities around the doll or around the doll, and an output signal of the electrical detection means It has a control circuit that determines the pitch according to the change, and the pitch determined by the control circuit changes in stages according to the scale.

  FIG. 1 shows a pitch calculated based on a physical quantity by an electronic musical instrument disclosed in Utility Model Registration No. 3118541. The pitch simply increases while showing discrete values, and is formed in a step shape. The discrete values indicate a plurality of pitches constituting the entire scale. Such an electronic musical instrument does not output musical tones having different pitches from a plurality of pitches constituting the western scale (all scales). For this reason, the performer can easily output only the musical tones having a plurality of pitches constituting the western scale (full scale) using the electronic musical instrument.

  There are songs that use not only the musical tones that make up the Western scale, but also the musical tones that make up the chromatic scale. Such music can be played using the electronic musical instrument configured to output a plurality of pitches constituting the chromatic scale. In such an electronic musical instrument, when the number of pitches that can be output is increased, the range of physical quantities corresponding to each of the pitches becomes narrower, and the movement of the pitch shifts slightly, so that the musical tone of adjacent pitches is reduced. Becomes easier to output. That is, the performer requires more skill in performance as the number of pitches that can be output increases. For this reason, such an electronic musical instrument is desired to be easier to operate when outputting musical tones of a predetermined scale even if the number of pitches that can be output increases.

  The control device 10 lights up and displays one floor name selected from the first scale based on the opening degree, and blinks one floor name selected from the second scale based on the opening degree. indicate. The control device 10 calculates the pitch based on the opening degree of the mouth 5 and the state of the scale changeover switch 15. That is, the control device 10 selects one pitch based on the opening degree from the first scale when the scale change switch 15 is not pressed, and the control device 10 presses the scale change switch 15 When selected, one pitch is selected from the second scale based on the degree of opening. The control device 10 further outputs a musical tone having the calculated pitch from the speaker 8 at a volume corresponding to the pressing force.

  According to such an operation, the player can easily play only the musical tones having a plurality of pitches constituting the first scale or the second scale, as compared with the operation in the glissando mode, as in the above-described embodiment. Can be output. In such an operation, the pitch displayed on the display device 18 is the pitch of the musical tone output in response to pressing of the pressing force detection device 14 when the scale switch 15 is not pressed. The pitch displayed on the display device 18 in a blinking manner indicates the pitch of a musical tone that is output in response to pressing of the pressing force detection device 14 when the scale switch 15 is pressed. At this time, the performer can check which musical tone is output according to the state of the scale changeover switch 15, and does not make a mistake in the pitch included in the second scale without being included in the first scale. Can be output.

  According to such an operation, the performer sets a pitch that frequently appears in a desired musical piece as the first scale, and sets a pitch that rarely appears in the musical piece as the second musical scale. According to such a setting, the average of the widths of the plurality of sections used when outputting the first scale is the average of the widths of the plurality of sections used when outputting the second scale. Because it is larger, the performer is included in the second scale without being included in the first scale while preventing the musical tone having the wrong pitch from being output when outputting the pitch included in the first scale. The pitch can be output. For this reason, the performer can perform the desired musical piece more easily using the electronic musical instrument according to the present invention.

  Note that the second scale may be set so as not to include all of the plurality of pitches of the first scale. At this time, it is preferable that the performer can freely set the first musical scale and the second musical scale so that the desired music can be played more easily. For example, the performer appropriately outputs the first musical scale and the second musical scale, so that an unnecessary musical sound can be output when a desired music piece is played with the pressing force detection device 14 being pressed (for example, , Compared to the Western scale mode), the music can be played more easily.

  Note that the display form in which the floor name is displayed on the display surface 28 of the display device 18 may be replaced with another display form. As the display form, a form in which two pitches are displayed side by side is exemplified. One of the two pitches indicates the pitch of a musical sound that is output in response to pressing of the pressing force detection device 14 when the scale change switch 15 is not pressed. The other of the two pitches indicates the pitch of a musical sound that is output in response to pressing of the pressing force detection device 14 when the scale changeover switch 15 is pressed. In this case as well, in the same way as in the above-described embodiment, the performer can confirm which musical tone is output according to the state of the scale changeover switch 15 and is not included in the Western scale. The pitches included in the chromatic scale can be output so as not to be mistaken.
