The method comprises the following steps: a. it uses the corresponding press key to input the order; b. the single machine unit finds out the stored standard sound code by the inputted order; c. it generates an audio signal output of the standard sound by the code and displays the name, group order, the arranged A4 value and the indicating sound on the staff sent by the outputting unit at the same time.
Description
Technical field
The invention belongs to the electronic musical instrument parts category, more specifically say to relate to a kind of pitching instrument and its implementation.
Background technology
The accuracy in pitch training is an important step of learning music, main judgment of cultivating the music-learner to accuracy in pitch, most of beginners do not possess accuracy in pitch judgment accurately, need carry out in a large number the training of ear-training repeatedly, the finger of strengthening some sounds by the sense of hearing touches the string position and the exercise of the dynamics of stopping, to control pitch accurately.
Traditional method is to reach and control accuracy in pitch accurately by allowing the music-learner carry out solfeggio training, but this needs special course training, spends the more time.Especially Chinese fiddle and violin etc. there is not sign indicating number position stringed musical instrument, not resembling piano, dulcimer and Chinese lute, guitar etc. has clear and definite pitch to play position and sign indicating number position, its accuracy in pitch must touch the string position by the sense of hearing and control finger, the dynamics of stopping is come Collaborative Control, more needs long study, training.
The conventional exercises method comprises: 1. mark phoneme scale on musical instrument, wish that the music-learner helps to solve the accuracy in pitch problem by vision, if but the phoneme scale is inaccurate, can cause music-learner's sense of hearing error.Even touch at finger under the situation of string correct position, also can lay particular stress on or light partially and produce the phenomenon of accuracy in pitch deviation because of the dynamics that finger touches string.2. play teacher's training mate method with the mellotron demonstration, need academics and students's cooperation in time so, be not suitable for student individual exercise.In addition, the difference that also lacks performance sound and corresponding with it unisonance high standard sound of these methods quantizes indication.
The electronics pitching instrument is a kind of device that can send each key of musical instrument or string standard voice, the standard pronunciation of sending out and actual musical instrument pronunciation comparison, thereby reach the purpose of proofreading and correct the musical instrument accuracy in pitch, present pitching instrument generally is to send the standard pronunciation of being stored one by one by single button or one group of two-way choice key, find required standard pronunciation, to could realize through repeatedly pressing button, make the music-learner be beyond expression to the height Changing Pattern that key or string pronounced adjacent or close in the musical instrument at all, both loaded down with trivial details not directly perceived yet, nor the pitch of energy display standard sound is difficult to the perceptual knowledge of pitch and the pitch labeling position in the music score are connected closely like this for music-learner and music-lover.
Summary of the invention
Technical matters to be solved by this invention provides a kind of accordatura process simpler pitching instrument that becomes that makes.It comes the choice criteria sound by piano type button, because it is corresponding with actual keyboards for musical instruments, so be easy to standard pronunciation that is sent and actual keyboards for musical instruments are mapped, simulation simultaneously shows the marker location of this standard pronunciation in the staff music score, operate both simple, also be easy to give expression to the key adjacent or close in the corresponding musical instrument or the height Changing Pattern of standard pronunciation that string is sent out
Pitching instrument of the present invention comprises single-chip microcomputer processing unit, key-press input unit, demonstration output unit, audio output circuit, it is characterized in that: described key-press input unit is provided with corresponding with actual keyboards for musical instruments one group of button and functional switch.
One group of above-mentioned button be one group can be luminous button.
Above-mentioned one group of button and functional switch are respectively piano type button, group preface options button and A4 value options button, the relation of actual keyboards for musical instruments correspondence is as follows: piano type button is set to totally 12 of SW11...SW32, sound group (octave) on the corresponding fingerboard, i.e. C, C#, D, E
b, E, F, F#, G, G#, A, B
b, B, press corresponding each sound group of group preface options button, range of choice is 0-8, the big word of the corresponding fingerboard of difference two groups of (A2...B2), big word one group of (C1...B1), big word groups (C...B), small character group (c...b), small character one group of (c1...b1), small character two groups of (c2...b2), small character three groups of (c3...b3), small character four groups of (c4...b4), five groups of small characters (c5), press A4 value options button and can change the A4 value, scope is an a certain round values among the 430-450Hz.
Owing to be provided with corresponding with actual keyboards for musical instruments one group of button and functional switch at key-press input unit, so come the choice criteria sound by piano type button, because it is corresponding with actual keyboards for musical instruments, so be easy to standard pronunciation that is sent and actual keyboards for musical instruments are mapped, also be easy to give expression to the key adjacent or close in the corresponding musical instrument or the height Changing Pattern of standard pronunciation that string is sent out, for music-learner and music-lover, be easy to the perceptual knowledge of pitch and the marker location of the sound in the music score are connected closely.
Two of technical matters to be solved by this invention provides and a kind ofly can make the accordatura process simpler method that becomes.
Method of the present invention may further comprise the steps:
A, by the corresponding key input instruction;
B, single-chip microcomputer processing unit find the standard pronunciation code of being stored according to input instruction;
C, single-chip microcomputer processing unit produce the audio signal output of this standard pronunciation according to code, when sending standard pronunciation, the musical alphabet of the display unit output standard pronunciation that sends, organize one of them or combination in any of preface or string preface, set A4 value.
Comprise also among the above-mentioned step C that display unit output simulation shows the marker location of this standard pronunciation in the staff music score.
Comprise also among the above-mentioned step C that the button identical with this standard pronunciation musical alphabet can luminous indication.
Method of the present invention is owing to can be mapped standard pronunciation and the actual keyboards for musical instruments that sends, thus be easy to give expression to the key adjacent or close in the corresponding musical instrument or the height Changing Pattern of standard pronunciation that string is sent out, very directly perceived; And can simulate the marker location that shows the staff middle pitch, for music-learner and music-lover, easily the perceptual knowledge of pitch and the pitch labeling position in the music score are connected closely.
