A scrolling type roll-call roll-call matching display device

Abstract

The invention provides a scrolling display device for pitch and syllable names matched along with a musical mode. The device comprises a pitch and syllable name display module, a scrolling module and an additional module, wherein the pitch and syllable name display module is used for displaying a fixed pitch name and a syllable name which is changed along with the musical mode; the scrolling module is used for changing the syllable name according to a manual or program control mechanical device for the musical mode; and the additional module is used for integrating the pitch and syllable name display module and the scrolling module, so that the scrolling display device can be conveniently dismounted from a key of a piano or conveniently mounted on the key of the piano, can be conveniently carried and can realize purely mechanical passive implementation. The device is placed above the key of the piano, the pitch name displayed on the scrolling display device is constant, and the syllable name changes manually or in a program control way along with the musical mode, so that a newbie favorably coordinates with sightsinging to rapidly learn the piano.

Description

technical field [0001] The invention mainly relates to a matching device of a keyboard musical instrument, in particular to a scrolling device for displaying both pitch names and roll names. Background technique [0002] Keyboard instruments generally refer to pianos, electronic organs, etc. The piano is composed of keys and a metal string soundboard. The player presses the keys on the keyboard, moves the small mallet covered with felt inside the piano, and then strikes the steel strings to produce sound. It is a mechanical device that produces sound. The piano emits sound through a mechanical device, which determines that the frequency of each key on its keyboard is fixed and has a fixed pitch. Pitch refers to the height of the sound, which describes a basic feature of the sound, and the height of the sound is determined by the vibration frequency. If the frequency is high, the sound is "high", otherwise it is "low". Obviously, the pitch of the piano keys is not adjustabl...

AI Technical Summary

Problems solved by technology

The staff notation uses five lines and four rooms to describe the pitch. Compared with numbered notation, the staff notation has the advantage that it is easy to display the pitch of the pitch, but the staff does not have a cyclic feature and is not designed based on roll call, so it is difficult to hum in five lines and four rooms Roll call is not conducive to sight singing
