Abstract
琴键练习指示装置涉及乐器教学领域，特别是琴键类乐器的教学。弹奏是一个熟悉过程，节拍是需要长时间练习才会掌握。当今的手把手教学生，其效率低下、费用昂贵。为提高琴键类乐器的教学效果、降低教学的劳动强度，本发明设计一种琴键练习指示装置。技术方案是：装置由电脑、信号线、控制器、导线、发光二极管组成。在电脑中，每首乐曲数据采用一个数据库文件存储，电脑的数据库数据通过程序和信号线传递到控制器，控制器翻译完成后，控制与每个琴键的发光二极管发光。有益效果是：将曲谱录入到数据库，开启控制系统，可以重复练习，减少教师的指导工作量；有利于学生准确掌握曲谱；也利于教学的快速传播和乐器的普及，降低音乐教学成本。
The keyboard practice indicating device relates to the field of musical instrument teaching, in particular to the teaching of keyboard musical instruments. Playing is a familiar process, and the rhythm needs long-term practice to master. Today's hands-on teaching of students is inefficient and expensive. In order to improve the teaching effect of the keyboard musical instrument and reduce the labor intensity of teaching, the invention designs a keyboard practice indicating device. The technical scheme is: the device is composed of a computer, a signal line, a controller, a wire and a light-emitting diode. In the computer, the data of each piece of music is stored in a database file. The database data of the computer is transmitted to the controller through the program and the signal line. Beneficial effects are: enter the score into the database, turn on the control system, repeat the practice, reduce the teacher's guidance workload; help students accurately master the score; also facilitate the rapid dissemination of teaching and the popularization of musical instruments, and reduce the cost of music teaching.
Description
Technical field
The present invention relates to the musical instrument teaching field, particularly the teaching of key kind musical instrument.
Background technology
Music is that note is arranged in chronological order, and bent writer writes out duration and the ordering of note, each note, and the player strictly plays by note duration and power, and the correctness of note order and corresponding duration characterizes player's level.
Play and be one and be familiar with process, beat is to need long-time exercise just can grasp.If teacher teaches by doing the student always, its efficient will be and be low, and labour intensity also is huge, and the student will obtain more outstanding teaching, and its tuition fee also will be relatively more expensive, and the universal of this musical instrument is restricted.
In science and technology relatively advanced today, adopt original instructing in words and by deeds, also fallen behind really very much.
Summary of the invention
Be the teaching efficiency that improves the key kind musical instrument, the labour intensity that reduces teaching, the present invention designs a kind of key exercise indicating device.
The present invention realizes that the technical scheme that goal of the invention adopts is:
The development degree of modern science and technology, the time precision of computing machine might be indicated each note duration and power by computing machine fully.
Device is comprised of computer, signal wire, controller, wire, light emitting diode.
In computer, every first music data adopts a data library file storage, data field comprises the power of per minute beat number, time series (take beat as chronomere), note, the duration of a sound (take beat as chronomere), beat, the time series starting point be 0,1/4 beat as 1,1/8 beat as 0.5,1/2 beat is as 2, by that analogy, whether note represents is 1-7 and high pitch, bass, semitone, and the duration of a sound is the time quantum (1/4 beat is as 1) that note continues.
The database data of computer is delivered to controller by program and signal wire, after the controller translation is finished, and the light emitting diode of control and each key, corresponding 2 light emitting diodes of each key, one glows, and the note of corresponding beat is strong; A green light, to note that should beat be a little less than, by the high level of wire output to this light emitting diode, then this light emitting diode is lighted, the time of lighting is by the control of note duration.
The invention has the beneficial effects as follows: when the music director teacher prepares lessons, only the exercise music score of Chinese operas need to be entered into database, behind instruction of papil, by opening control system, the student can repeat exercise, reduces teacher's guiding work amount; By the fluorescent lifetime of light emitting diode, the beat of accurately pointing out student's button to continue is conducive to the student and accurately grasps the music score of Chinese operas; Because database can copy, can once work, use many places, reduces the duplication of labour, also is beneficial to the fast propagation of teaching and popularizing of musical instrument, reduces the music teaching cost.
Description of drawings
Fig. 1 is key exercise indicating device.
Wherein, 1, computer, 2, signal wire, 3, controller, 4, wire, 5, light emitting diode.
Embodiment
In computer 1, adopt data database storing, data field comprises time shaft sequence (beat), note, the duration of a sound (beat), the time shaft starting point be 0,1/4 beat as 1,1/8 beat as 0.5,1/2 beat is as 2, by that analogy, whether note represents is that and high pitch, bass, the semitone of 1-7, and the duration of a sound is the time quantum (1/4 beat is as 1) that note prolongs.
The database data of computer 1 is delivered to controller 3 by program and signal wire 2, after controller 3 translations were finished, the light emitting diode 5 of control and each key was at high level of wire 4 outputs of this light emitting diode 5, then this light emitting diode 5 is lighted, and the time of lighting is controlled by the duration of a sound.
Note and high pitch, bass and semitone, can be defined as a field, also can be defined as two fields even three fields, such as 310,320,315,325 basses that can be expressed as respectively note 3 (with 1 expression), high pitch (with 2 expressions) and semitone (representing with 5), the efficient that how much generally depends on equipment of field, the efficient of equipment is high, and field can be more, and logging data is simplified.
Claims (3)
1. key exercise indicating device is comprised of computer, signal wire, controller, wire, light emitting diode, it is characterized in that: in computer, every first music data adopts a data library file storage, database data utilizes program to be delivered to controller by signal wire, after controller translation is finished, thereby control light emitting diode luminous of the wire level control position of piano key of each light emitting diode.
2. key according to claim 1 is practised indicating device, it is characterized in that: corresponding 2 light emitting diodes of each key, and one glows, and the note of corresponding beat is strong; A green light, to note that should beat be a little less than; At high level of wire output of this light emitting diode, then this light emitting diode is lighted, and the time of lighting is by the control of note duration.
3. key according to claim 1 is practised indicating device, it is characterized in that: data field comprises the power of per minute beat number, time series (take beat as unit), note, the duration of a sound (take beat as chronomere), beat, the time shaft starting point is 0,1/4 beat is as 1,1/8 beat as 0.5,1/2 beat as 2, by that analogy, whether the expression of note is 1-7 and high pitch, bass, semitone, and the duration of a sound is the time quantum (1/4 beat is as 1) that note continues.
