Abstract

The invention discloses a scale identifier comparing device for a urheen, which comprises a sound track film and a bottom plate. The scale identifier comparing device is characterized in that notes are carved on the sound track film which is arranged in a groove of the bottom plate; one end of the sound track film is sleeved on a drum of an adjusting shaft, and the other end of the sound track film is sleeved on a rotary shaft which can rotate synchronously with the drum and the sound track film; the adjusting shaft can be adjusted up and down in an adjusting groove of the bottom plate and is fixed through a clamping bolt; and two arc clamps are arranged at the bottom of the bottom plate. The scale identifier comparing device is installed below the bridge on the urheen rod, so that a beginner of urheen can see and compare when pressing the strings, a strong foundation for acoustical discrimination ability is established, and the beginner can master intonation at a primary stage; and particularly, the device can directly provide correct basis and prompt of scale, notes and intonation for learners with defect in hearing. Therefore, the invention is remarkably helpful in mastering and improving the urheen playing skill quickly.

Description

A kind of scale sign comparison device of Chinese fiddle

Technical field:

The present invention relates to a kind of national bowed stringed instrument, be specifically related to a kind of scale sign comparison device of Chinese fiddle.

Background technology:

The performance of study Chinese fiddle musical instrument is a very difficult thing, particularly especially difficult to the assurance of accuracy in pitch, it is unlike the musical instrument of learning other, as blowing instrument, the keyboard musical instrument, it is porose on these musical instruments, have strong, the accuracy in pitch ratio is easier to grasp during study, beginner for Chinese fiddle, how to grasp the accuracy in pitch of performance, be puzzlement beginner's a big technical barrier always, and especially audition shortcoming person is all the more so, tend to cause learning the long-time incessantly skill of accuracy in pitch of grasping of personnel of Chinese fiddle, influence the progress of whole study Chinese fiddle, both expended a large amount of learning times, can not reach good playing effect again.

Summary of the invention:

Purpose of the present invention will solve the deficiencies in the prior art exactly, and a kind of scale sign comparison device that can fast, accurately grasp a kind of Chinese fiddle of Chinese fiddle accuracy in pitch is provided,

For achieving the above object, the technical solution adopted in the present invention is: a kind of scale sign comparison device of Chinese fiddle, comprise vocal cores film, base plate, it is characterized in that: on the vocal cores film, be carved with note, the vocal cores film is arranged in the groove of base plate, one end of vocal cores film is enclosed within on the rotating cylinder of regulating shaft, the other end of vocal cores film is enclosed within the rotating shaft, rotating shaft can be rotated synchronously with rotating cylinder, vocal cores film, but regulating shaft is up-down adjustment in the regulating tank of base plate, regulating shaft is to fix by fishbolt, and two arc cards are set in the bottom of base plate.The present invention is installed in the very heavy lower position on the Chinese fiddle bar, make the beginner of Chinese fiddle can watching, contrasting when stopping, for the discrimination ability of the sense of hearing is laid a solid foundation, the primary stage just can be well accuracy in pitch in hand, especially can directly provide the accuracy in pitch foundation and the prompting of scale, note accurately to audition shortcoming person, to grasping and improve the playing technique effect of being very helpful of Chinese fiddle as early as possible.

Description of drawings:

Figure is the scale sign comparison device synoptic diagram of Chinese fiddle.

1 is that vocal cores film, 2 is that base plate, 3 is that regulating shaft, 4 is that rotating shaft, 5 is that rotating cylinder, 6 is regulating tank 7, is that fishbolt, 8 is that arc card, 9 is that groove, 10 is a note.

Embodiment:

The invention will be further described below in conjunction with accompanying drawing, as shown in the figure, the scale sign comparison device of a kind of Chinese fiddle involved in the present invention, comprise vocal cores film 1, base plate 2, it is characterized in that: on vocal cores film 1, be carved with note 10, vocal cores film 1 is arranged in the groove 9 of base plate 2, one end of vocal cores film 1 is enclosed within on the rotating cylinder 5 of regulating shaft 3, the other end of vocal cores film 1 is enclosed within the rotating shaft 4, rotating shaft 4 can with rotating cylinder 5, vocal cores film 1 rotates synchronously, but regulating shaft 3 is up-down adjustment in the regulating tank 6 of base plate 2, and regulating shaft 3 is fixing by fishbolt 7, and two arc cards 8 are set in the bottom of base plate 2.Arc on the use device of the present invention fastens the very heavy lower position on the qin bar, make the first row note on the vocal cores film of this device accord with corresponding with empty-chord sound on the Chinese fiddle, can be by rotating the rotating shaft on this device, the piano practicer demonstrates the position of the scale note of respectively tuning up, for can directly provide accuracy in pitch foundation and prompting accurately.
