The guitar is unstable, what the hell is wrong

Find the three points of support.

One is the recess under the case, the point on the legs, and the other is the point on the body that is recessed on the top of the piano.

The third is the point where the right arm is placed on the case.

After finding the three points, the feeling of a tripod is formed. Make sure that you let go left and right without shaking, so that you won't have a problem bounce.

Is it because it's too skinny or a turtle's back harp, try to tilt your leg to the other leg.

Tilt the right leg up at an angle of 45 degrees, and it should be a little more stable.

It's not about the arm, or your body is not relaxed, the most critical thing for beginners to learn musical instruments is the state of the body, most people will make themselves very nervous when they learn guitar, hold the guitar and the same as the end gun, tilt the body center of gravity slightly to the left hand, from the shoulders to the forearm, wrist, fingers must remain in a natural relaxed state, if you play the piano for a while your shoulders and forearms have a feeling of soreness, it means that your muscles are still tense, stop at this time, continue to find a feeling of relaxation, many beginners feel that this kind of exercise is not necessary, I'm always anxious to play some tunes or something, but I don't know if playing the piano can relax or not, which directly determines how far you can go on the guitar road in the future.

Try a different piano, a different barrel type. The 41-inch Dreadnought barrel type (D barrel type) and the 40-inch Auditorium barrel type (A barrel type), OM barrel type, and Taylor barrel type. Common of these ...

The PT-700 of the Venetian guitar is a D barrel type with rounded corners, the PT-62C is a D barrel type with a missing corner, the PT-66 is an OM barrel type, the PT-67C is a Taylor barrel type, and the PT-68 is a A barrel type. For barrel type reference only.

It is also possible to correct the posture, not necessarily according to other people's standards, there is no fixed posture for the folk guitar.

Listen to what you said about this situation, as if this piano is much bigger than you, if this is the case, then this is the most direct impact, the choice of the piano should be chosen in line with their own figure, if it is not suitable for it, there is really no way, continue to play may be due to the posture for a long time incorrect resulting in the wrong stereotype, it is recommended that you change to a slightly smaller piano, this one will wait for you to grow up and talk about it.

It may be that your legs are too thin, so you can bend your legs, I think so, don't be surprised!

It's really like holding the guitar as your wife, it's definitely holding it steadily, hehe.

The posture is not right, first look at the guitar textbook to teach you the correct posture, to make the left hand without touching the piano body to maintain stability, and then start to learn or play the piano. Otherwise, it will affect future learning. There are also teachings on the Internet**, search for the first lesson to see the basics, and they are generally taught.

Pay attention to three or four points of contact between the body and the piano, and it is relatively easy to find the feeling.

Any method is to feel it, don't be too standardized, feel the most comfortable and reasonable thing yourself!

It depends on how you take it, the concave place is placed on the thigh, and the left hand should be able to play a fixed role while pressing the strings, and the right elbow is also placed on the guitar, so it shouldn't be unstable.

It's not about the arm, or your body is not relaxed, the most critical thing for beginners to learn musical instruments is the state of the body, most people will make themselves very nervous when they learn guitar, hold the guitar and the same as the end gun, tilt the body center of gravity slightly to the left hand, from the shoulders to the forearm, wrist, fingers must remain in a natural relaxed state, if you play the piano for a while your shoulders and forearms have a feeling of soreness, it means that your muscles are still tense, stop at this time, continue to find a feeling of relaxation, many beginners feel that this kind of exercise is not necessary, I'm always anxious to play some tunes or something, but I don't know if playing the piano can relax or not, which directly determines how far you can go on the guitar road in the future.

It's normal to start out with some uncontrollable guitars. It's good to get used to it. It's not about the arm.

No, I'm a little over 170 too. Under the more run-in, the guitar rests on the chest, the thighs are placed diagonally, 3 points of support, the hands are leaning on the back of the arc, and the hands are almost at the position of the sound holes, and they hang down naturally.

Xiu has to change the line! The nails are a little longer, after all, the film is not pleasant to pick up, and I often touch the strings, which may be too high in grade and not accurate. Sometimes it's my own feeling that the sound is not as good as before, or that it is better than before.

You still have to fiddle with the guitar more, so that the best protection of the strings, talk a lot, play it with a lot of feeling, and the timbre problem will gradually become gone!

The criterion for changing the spin is that the sound of the guitar has not changed much after changing the spin, if you find that the sound of the guitar is significantly different from before after changing it, it means that your Xuan should have been changed a long time ago, and the cycle of changing the spin depends on your situation.

It's good to play more and practice more.

It may also be that the nails are not well repaired, a little sharp, and there is a brand of strings to be used, and the six are changed together when you are happy.

The unsteady press may be due to the lack of strength for beginners, so you need to practice more, and when you are familiar with it, you can press it steadily and change chords quickly.

You have to practice the guitar like this, you have to be willing to take time, you practice, even if the action is slow, you practice many times, you will slowly have a feeling, if you press it unsteadily, you can only pay special attention to it every time you press it, and when you get used to it, you will press it steadily.

You are a new string, don't worry, it's all like this, tune all six strings like this, play and tune at the same time, and after a day or two, it will be basically stable. That's it every time you change the strings.

It may be that the strings of the guitar are loose, you can take it to the piano store and have someone check it for you, it doesn't cost much.

What kind of piano do you use? With a double shake? The description is a little more detailed.
