Description

Intelligent keyboard instrument exercise system

Technical Field

The invention relates to the technical field of auxiliary learning of musical instruments, in particular to an intelligent keyboard musical instrument exercise system.

Background

In this age of abundance, more and more families will choose to purchase instruments as children age, for interest or other reasons. Musical instruments include pianos, electronic organs, and the like, of which the piano is most used. Generally, a piano training mode is that a child goes to a training mechanism with a parent and is in one-to-one guiding practice with a professional teacher after making an appointment in advance. But the exercise time is probably only 1-2 lessons per week, which is far from enough; it also requires a lot of time to exercise at home at ordinary times. However, the professional piano teachers have a very expensive course, children are in a stage where interests are easy to change, many children give up due to boring practice under the condition of no guidance at home, and high-priced purchased pianos are idle quickly.

In order to solve the problems, a plurality of piano auxiliary exercise device products, such as a product called an intelligent piano, appear on the market, wherein a tablet personal computer is configured on the piano, when the piano is exercised, partial virtual key images are displayed on a screen, the color can be changed according to the music note sequence, but the problems of non-intuition and time judgment are solved, because when the piano is exercised, after human eyes receive information, a brain judges and calculates according to the images, and corresponding keys on the real piano are selected to be pressed; in the whole switching and converting process, the brain has time delay during judgment, and thinking time is in a state of interruption and connection. In addition, CN 208569922U discloses a piano auxiliary exercise device and system, it is to place 88 pilot lamps in a long tube, and the long tube is installed above the key, and the intraductal small lamp shines according to the musical note order, and the practitioner pushes the key that the small lamp corresponds according to the small pilot lamp suggestion. Similar products are also found in the market, which mainly changes a single lamp in CN 208569922U into a plurality of lamp strings. Although the scheme is intuitive compared with a screen intelligent piano, the indicating lamps are arranged on the side of keys far away from a human body, the key pressing position is far away from the key pressing position of the hand, under the condition, after the light is seen by human eyes, the key corresponding to the straight line of the indicator light needs to be judged and selected, the black semitone keys on the keyboard are arranged between the two white keys, after the light is seen by human eyes, the brain needs to construct a virtual straight line from the light part, whether the light corresponds to the black keys or the white keys, whether the light corresponds to the left white keys or the right white keys, in addition, the black keys are higher than the white keys by nearly one centimeter, 88 keys in the whole piano keyboard region are about 130 centimeters from left to right, when human eyes look obliquely, the black keys partially or completely block the rear half part of the white keys, visual errors are easily formed between the sight lines and distant targets, the above problems cause errors in judging the keys corresponding to the lamp and the straight line, or delay the judgment time of the brain. In addition, the additional devices on the keyboard are too many, and the number of the lamps is too many, so that the keyboard is disordered in vision. In addition, the scheme only prompts keys, and does not prompt which finger should be used for pressing specifically, a trainee needs to give a finger in a very short time in the piano playing process, a beginner can use a large number of index fingers or middle fingers according to habit convenience to form wrong fingering habits, or frequently recall learned finger using sequences, and select the fingers through brain thinking judgment to cause time delay.

Therefore, the development of the intelligent keyboard instrument training system which is intuitive in use and does not need subjective consciousness judgment of people is of great practical significance.
