The harmonica pronunciation is a little trembling, is it normal, how to blow the harmonica vibrato

A subtle vibrato should be normal. The tones of the upper and lower compartments of the polyphonic harmonica are not exactly the same, there are subtle differences, and there will be this "vibrato" when blown at the same time. However, this kind of vibrato is too pronounced and the amplitude is too large (due to the large difference in the pronunciation of the upper and lower reeds) is abnormal.

You can take it apart and adjust it yourself. Blow by yourself, compare the pitch of the upper and lower grids, and gently scrape the end of the low-pitched reed with a razor blade. If you can't hear it by ear, it's best to find a tuning software on the Internet, and you can intuitively see the value for fine-tuning by blowing on the microphone.

No, don't worry, it's normal!!

The timbre of the polyphonic harmonica is characterized by this. The polyphonic piano hole is divided into two rows, and when generally blowing, the upper and lower reeds in the same hole sound at the same time. Due to the slight difference in the frequency of the vibration of the two reeds, the simultaneous vibration produces a phenomenon called "beat", which is manifested as a periodic change in the intensity of the sound, which is called "tremolo".

I think that's what my predecessors said, "the pronunciation is a little trembling", right?

Not normal, several reeds of this tone are not in harmony with each other. You need to find an organ repair master.

Normal, do you look at the upper and lower positions of the pronunciation reeds that are too wrong? If the staggered distance is far away, you need to repair the pronunciation reed.

The next time you play, make the harmonica hole perpendicular to the airflow, which will reduce the occurrence of vibrato!

1. Hold the harmonica with the tiger's mouth with your left hand, and try to bring the fingers of your left hand closer together to form a bowl shape. The right hand rests on the bottom of the instrument. This allows you to blow a vibrato with the opening and closing of your right hand!

2. The harmonica vibrato is to move rapidly between the two adjacent sound holes of the harmonica, resulting in a vibrato effect. Although Zhao Pei Bi Ran uses the handheld piano to move quickly left and right, and the head can quickly move left and right to achieve the same effect, it is still recommended to use the head to shake the method from side to side. This is easier for beginners to master.

This has nothing to do with lung capacity.

There are two reasons for the sound trembling, one is the reason for the harmonica: you try to see if there is only one hole trembling, or only inhalation trembling, if only a few holes have this phenomenon, that is the reason for the harmonica, if it is estimated that the landlord uses a polyphonic harmonica, the general polyphonic harmonica will have this situation, don't care too much about these.

The second is the cause of airflow: sometimes the airflow is discontinuous or large or small, and this effect similar to laryngeal tremor will appear.

These are the two reasons in general, and I hope it can help a little

This is your lack of qi, just contact your lung capacity more.

And tremble, sometimes it can also be used as a decoration in the song!

You should be referring to the [double-sided two-tone polyphonic harmonica]. It is also known as [24-hole 48-tone double-sided harmonica]. It is equivalent to two harmonicas of different tones combined.

This harmonica is most often in the key of C G, followed by the key of C D and the key of C A, etc. Because of the arrangement of the harmonica with blows on both sides (equivalent to one side and one side), it may hinder each other and affect the source space of the harmonica sound, so a considerable part of the blowings are pushed out on the holes on both sides of the harmonica. There are holes on both sides to push out the sound holes, so you can make a vibrato by covering the holes with your hands, and the frequency and rhythm of the hands are open and closed, which is somewhat similar to the vibrato effect of the polyphonic harmonica's [hand tremolo] technique.

The tone and playing skills of this harmonica are enriched.
