Description

微电脑控制的数码弦乐器 Microcomputer control digital stringed instruments

技术领域 FIELD

[0001] 本发明涉及弦乐器技木,尤其涉及一种微电脑控制的数码弦乐器。 [0001] The present invention relates to a stringed instrument wood technology, in particular, relates to one kind of stringed musical instrument digital microcomputer control.

背景技术 Background technique

[0002] 现有的小提琴包括弓子、琴头、琴身和设于琴头与琴身上方的琴弦,其中琴头包括指板。 [0002] Existing violin bow comprises a headstock, piano strings and piano and provided on the headstock side of the body, wherein the headstock comprises a fingerboard. 当练琴者按弦接触指板的正确音准位置时,可以发出悦耳的演奏音乐。 When practicing person to the string contact finger plate correct pitch position may be issued sweet playing music. 小提琴的指板是一本身无音准位置限制而是靠演奏者演奏时左手指尖按弦触及指板产生其音准概念的ー个装置,但每个音的音准位置实际上是存在于指板上的,其音准是要经过学琴者较长时间的严格训练而获得其位置感,以及获得从听觉到手指对音准反应的灵敏度,从而在演奏时达到较好的音准状态。 Refers to a violin plate itself has no position regulating pitch but from which the concept of pitch on the left hand fingers touch the finger plate to the string player plays the ー a device, the position of each tone pitch is actually present in the fingerboard , the pitch is to go through rigorous training and a long-time piano's get a sense of its position, and obtain from the auditory sensitivity to finger pitch reaction, so as to achieve a better state of pitch you play.

[0003] 进ー步地,小提琴的弓子和琴弦的位置关系(如上弓、下弓)、压カ关系(即弓压)、弓子在琴弦上的轨迹(运弓轨迹)和弓子在琴弦上的速度(即弓速或运弓速度)等都是影响演奏/小提琴发音的重要因素。 [0003] The positional relationship between the intake ー step, the bow and the strings of the violin (as bow, the bow), the relationship between pressure grades (i.e. arch internal pressure), the bow on the strings trajectory (trajectory bow) and bow in the piano speed on the string (ie, speed or bow bow speed) are important factors in playing / pronunciation violin impact. 通常,音量和弓速、弓子离琴码的接近程度成正比,且弓压需要随弓子接近琴码而増大,但又必须小于一定的值。 Typically, the volume and speed of the bow, the bow away from the proximity of the saddle is proportional to the pressure and the need to bow with the bow closer to the saddle zo large, but must be less than a certain value.

[0004] 故,对于初学小提琴的学生来说,初期很难掌握小提琴的音准,以及很难掌握弓子和琴弦的位置关系,尤其是在训练阶段,无法较好的掌握其位置关系,即学生在练琴时所发生的为自己所无意识到的错误位置关系和音准,往往要等一周后或何时去专业老师那儿上课时才能由老师指出,而这时学生的听觉上已习惯于平时的音准和右手的运弓姿态、力度,再纠正起来需花费较长的时间和精力。 [0004] Therefore, for the students begin to learn the violin, it is difficult to grasp the early violin intonation, as well as difficult to grasp the positional relationship between the bow and the strings, especially in the training stage, unable to better grasp their positional relationships, namely students when practicing what happened was not aware of their own mistakes and the positional relationship between pitch, often have to wait a week later when there or go to a professional teacher in class by the teacher to point out, but this time the students have been accustomed to hearing the usual right intonation and bowing posture, strength, and then correct it will take a long time and effort.
