Abstract

The invention provides a technical scheme of a piano. According to the scheme, a computer switch, a computer display, a computer hard disc, an optical disc drive, a computer power supply, a computer main board and a computer host consisting of USB (Universal Serial Bus) interfaces and network interfaces are arranged on a surface plate of a piano body; a keyboard support plate for holding a computer keyboard and a mouse is arranged at the bottom side of a key board base of the piano; a rear pressing sensor is arranged at the tail end of each piano key; the pressing sensors are electrically connected with a rear circuit board; the rear circuit board is further electrically connected with the computer main board; white key pressing sensors and black key pressing sensors are arranged in the middle of white keys and black keys of the piano and are all electrically connected with a middle circuit board; the middle circuit board is further electrically connected with the computer main board; speed sensors and optical-magnetic sensors are arranged at the front ends of the white keys and the black keys of the piano and are all electrically connected with a front circuit board; the front circuit is further electrically connected with the computer main board; sensing pieces are arranged inside cavity grooves in the bottom sides of the front ends of the white keys and the black keys; a page turning button is arranged on one side of the piano keyboard; a page turning pedal is arranged on one side of a bottom pedal group of the piano body.

Description

Technical field: [0001] The invention relates to a musical instrument for playing, especially a piano which can be combined with computer display scores. Background technique: [0002] In the prior art, known various upright pianos, grand pianos and electronic pianos are all independent pure sounding devices, and they are placed separately from the music score, and the person who buys the piano must purchase the music score in addition, and the accumulation of the music score is also limited. There will be more and more, and more and more space will be occupied. When using it, it is extremely inconvenient to leave the piano to find the music score. When using traditional printed music scores to read and play, it is often necessary to turn the pages of the score, which requires the use of the left or right hand being played, which also affects the performance and distracts the player's attention. Existing pianos, the tunes played on the piano cannot be automatically recorded...

Problems solved by technology

[0002] In the prior art, known various upright pianos, grand pianos and electronic pianos are all independent pure sounding devices, and they are placed separately from the music score, and the person who buys the piano must purchase the music score in addition, and the accumulation of the music score is also limited. There will be more and more, and it will take up more and more space. When using it, it is extremely inconvenient to leave the piano to find the score

It is often necessary to turn the pages of the score when using the traditional printed score to read the score, and it needs to use the left or right hand that is playing, which will also affect the performance effect and distract the player's attention

Existing pianos, the tunes played on the piano cannot be automatically recorded in real time and form a score. Professional composers also often use computers to record the tunes they conceive, but the computer and the piano are separate, and MIDI is required. Interface and MIDI keyboard to play scores, and the recorded staves are also imperfect, and need to be manually modified, which is troublesome, and the recording ability is also quite limited. These are the shortcomings of the existing technology
