Description

 The proposed electric musical instrument relates to the production of electric musical instruments and playing these instruments.

 Known electric musical instruments with piano and button keyboard.

 The ready-elected button accordion described in the book of Onegin A. "School of playing the ready-chosen button accordion" was adopted as an analogue. - M.: Music, 1976, p. 3. An electromusical instrument described in A.S. was adopted as a prototype. USSR SU 1631579 A1, 02.28.1981.

 In the book of Onegin A. "School of playing the ready-button accordion" describes the ready-button accordion having a case consisting of 2 halves connected by pneumatic fur. The left hand strap and the left button keyboard, consisting of 120 buttons, are located on the left half of the case, and the last 3 or 4 rows (counting from the fur) can be switched to the selectable range, the sounds of which are located like this: low sounds are at the bottom, and the upper sounds are up. The right button keyboard is located on the neck, mounted on the right half of the case, and consists of 3 or 5 rows, where the sounds are arranged as follows: low sounds are at the top and high sounds are at the bottom. Shoulder straps are located on the right half of the case. The button may be multi-timbre. Disadvantages of the analogue: the right and left keyboards are different: the left one is button-based, the right one is button-shaped, the sounds on the left keyboard are vice versa than on the right one. The left hand strap limits freedom of play on the left keyboard. It is impossible to use the thumb of the left hand when playing. On the left elective keyboard, it is difficult to execute sequences of sounds in thirds, sexts and octaves legato (legato - connected). When driving, the left hand gets tired.

 Prototype 1631579 A1 - an electric musical instrument that has the same right and left keyboards of the button accordion type, has the same drawbacks as a ready-made button accordion, except that it does not have fur.

 All these disadvantages are absent in the proposed multi-timbre electric musical instrument with mirror-symmetric 6-row keyboards of the bayan type.

 The proposed electric musical instrument is shown in figures 1, 2, comprises a housing 1 with a sound-forming system enclosed in it, shoulder straps 2 located on the housing 1, timbre and band 3 switches located on the housing 1, a volume pedal 9 with an electric cord, loudspeakers (small 5, built into the housing 1, and large 10 - external speakers), power cords 6, 7, 8 and external power plugs, right and left 6-row button mirror-symmetric buttons 4, each consisting of 2 three-row keyboards of bayan type (os ovnye keyboard A and A ', auxiliary - B and B'). The sound range of the auxiliary keyboards B and B 'can be switched an octave lower than that of the main keyboards A and A'. The power supply can be either external from the mains or internal, built into the housing 1, from batteries or from a battery. Both the right and left keyboards have the same scale. Volume pedal 9 is used to change the overall volume of both keyboards. To change the volume of individual sounds on both keyboards, an individual volume change can be provided in the sound-forming system. An automatic rhythm chord accompaniment may be provided in a sound generating system. Button 11 serves as an external or internal power switch. The essence of the proposed electric musical instrument is that the 6-row mirrored-symmetric keyboards of the accordion type correspond to the design of the hands of the musicians as much as possible, it’s convenient to use the thumbs of both hands when playing, it’s convenient to take low bass sounds, especially with your left hand, it’s convenient to play thrash, sext and octave sequences of legato (legato). The proposed electric musical instrument can be used as a solo and as an ensemble instrument.
