Description
Technical Field
The invention relates to the technical field of music rhythm control instruments, in particular to a music rhythm control device.
Background
Metronomes are the most commonly used music rhythm training tools, and users adjust the metronomes according to the number and speed of music scores to make them produce clicks with different rhythms. This click sound serves as a judgment scale for judging whether or not the performance tempo is accurate. The process of practicing using metronomes is boring. Therefore, many beginners are reluctant to use metronomes. The metronome is not directly related to the music score, and when a trainee negligibly or learns that the error occurs to cause the metronome problem, the metronome is difficult to find. In order to solve the problem of metronomes, there is a way for the trainee to follow the standard musical performance. When the start-stop time of the trainee does not accord with the standard music, the beat of the trainee is wrong. The standard music can be standard manual demonstration or synthesized by a computer according to music scores. This approach allows the trainee to easily find his own questions, but the trainee may still grasp the bad exact point in time when the note ends without a prior hint, the next time the exercise is performed. Another further method is to attach a beat click to the music synthesized from the score by the computer. The click sound has a certain cue for determining when the note has ended. But the effect is still limited for the case where the note end time is not at the beat point. For example, a 2/4 beat score has a measure of quarter notes and eighth notes, with the quarter notes ending at exactly the middle of the two clicks.
In summary, currently, there is no simple and direct method for rhythm training, so that most music learners have the problem of unstable rhythm in the first few years.
If a music rhythm control device can achieve the limb training effect of children and can send out different music tones through operating training equipment, the device capable of adding the interest of the limb training of the children needs to be innovated continuously.
