Drawings
FIG. 1 is a flow chart of a method for automatically teaching musical instruments and singing songs using computer software according to the present invention;
fig. 2 is a schematic view of the structure of the piano of the present invention.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings, as shown in fig. 1-2.
In this embodiment, in a first step, preparation: establishing physical simulation models for the sounds of various musical instruments, calling the models by using a software algorithm to realize the simulation of the sounds of the musical instruments, realizing a synthesizer of the sounds, editing music into symphony, digitizing the symphony into international standard MIDI files, respectively using different channels for the performance of the various musical instruments of the symphony and the left and right hands of the various musical instruments, adding lyrics TEXT files corresponding to each musical note, then encrypting, compressing and packing the two files into a small-size multi-meter Soxhlet DMS file, automatically generating corresponding waterfall spectrums by software according to the corresponding musical instruments and the music, collecting the sounds of the various musical instruments by a method of voice recognition reference frequency in the process, facilitating teaching,
secondly, designing a piano with special keys: the keys are extended to the edge of one side of the opposite surface of the user, so that when the piano is placed in front of the screen, the entity keys can be completely jacked onto the screen, the key prompts on the software keys corresponding to one by one on the waterfall spectrum of the screen directly indicate the corresponding entity keys, in the process, the user can conveniently play the piano along with the key prompts corresponding to one by one on the screen, the teaching effect is better,
thirdly, designing a piano with adjustable height: the height of the support of the piano is designed into a plurality of boards, and the heights of the boards are respectively: 1cm, 2cm, 4cm, 8cm, 16cm, 32cm and 64cm, and the like, wherein the height of the rear wood board is twice as high as that of the front wood board, in the process, by a power series polynomial expansion method based on 2, the user can stack the wood boards at will to realize any integer height within 1cm to 127cm, so that keys of a piano and keys on a screen waterfall spectrum can be aligned one by one, the height of the piano from the ground needs to be adjustable, and the piano is safe and stable,
fourth step, mode selection: putting the piano in the screen the place ahead for the physical key corresponds with the software key on the screen one by one, adjusts the piano height, places the software key window below on the screen in the physical key height, and the user selects corresponding teaching bullet mode as required: when the software demonstrates the playing mode, the waterfall spectrum flows downwards and plays notes, and color bars corresponding to the notes flow downwards to the other side of the user corresponding to the entity keys, so that the user can observe in real time; in the software teaching playing mode, the waterfall spectrum flows downwards and plays notes, and color bars corresponding to the notes directly fall on corresponding entity keys, so that the user can observe in real time; when the software teaching is in a playing mode, a user can select one or more channels for playing the teaching; the channels which are not selected by the user are automatically played, the notes of the selected channels are not sounded, and the user needs to wait for all the notes of the channels to be pressed by the user, so that the waterfall spectrum continues to flow downwards and other notes are played; because the user can arbitrarily modify and adjust the length, the width and the position of the piano keys on the software key window on the screen, if the width of the software keys on the software key window on the screen is aligned with the left and right of the keys of the entity piano which the user is playing, and the keys of the entity piano are contacted with the screen as much as possible, the software keys on the key window and the entity keys are in one-to-one correspondence, and the automatic teaching playing of the piano can be realized; when the software game plays the musical instrument mode, the notes of the channel selected by the user do not wait for the user to play downwards continuously until the user presses the key, but judge the key time of the notes when the notes reach the vicinity of the uppermost edge of the key window, count the score according to the amount of time difference, count the score according to the time difference of the downward flowing color bar corresponding to the notes of the time length of the keys of the user, and count the score according to the difference of the strength of the keys of the user and the strength of the notes; the playing time is counted to obtain a total score, so that the user can feel like playing a game, the interestingness and the challenge are increased, the playing effect is convenient to detect, in the process, the user can be better taught by selecting different modes, the interestingness is increased, the piano entity can be other musical instruments, and the sounding keys of notes in the music are corresponding to the notes of the piano entity and the notes of other musical instruments, so that the piano playing modes can be realized by only pressing the sounding keys of the notes of the musical instruments; the note color bars can be replaced by patterns, thereby increasing the interest,
fifth step, voice recognition: when a user plays a piano or other musical instruments or sings, the microphone collects sounds in real time, the filter eliminates noise, the processed sound signals are transmitted into the computer, the computer judges the sounding state of the key or the note of the entity key of the user at the moment through software analysis and calculation, meanwhile, the difference value between the standard frequency information of the key of the user's bullet obtained through identification and the standard sound corresponding to the key is displayed, the obtained state information is transmitted to a software key window, the key state is simulated and displayed, and in the process, the user can accurately see the state of playing the piano or singing, so that the rhythm, the tone quality and the tone quality of the sound can be conveniently adjusted in real time.
The above technical solution only represents the preferred technical solution of the present invention, and some changes that may be made by those skilled in the art to some parts of the technical solution represent the principles of the present invention, and the technical solution falls within the scope of the present invention.
