The sound of some instruments sounds loud to the ear, but there is no sound from a distance. Some instruments may sound loud when played alone, but when played together with other instruments, the sound becomes inaudible. Some pianos are played in an empty and deserted concert hall, with very good and loud sounds; But when the concert hall was filled with listeners, the sound became very soft and weak. And we are often surprised to find that those ancient Italian famous pianos, in the hands of excellent performers, have a sweet and loud sound, and their voices can fill every corner in a crowded concert hall. This is the issue of the violin's penetrating power.

Why do some guitars have good penetration ability while others do not?

The penetrating power of a violin comes from the resonance ability of the instrument. An excellent violin must have sufficient vibration ability, that is, it has a good driving force. A piano with a driving force will have the ability to penetrate. A poorly made factory piano often has issues with the accuracy of its board thickness, and its vibration ability is limited. Therefore, its penetration ability is even more limited.

Furthermore, the sound of the qin should be bright and not too low. According to the principles of physics, the transmission capability of high frequencies is much better than that of low frequencies. The high pitched sound of the qin can produce more high-frequency vibrations. No wonder the sound of the violin can travel farther than that of the viola and cello.

At the same time, the violin should also have a lot of overtones. The combination of fundamental and more overtones in a musical sound results in stronger penetration ability. A violin that has been played for a long time will have more overtones than an unused new violin. So generally speaking, the penetration ability of the old qin's sound is better than that of the new qin.

How can we check if the piano has penetration power?

I have tried two methods to simulate the amplification and absorption effects of a music hall, are they correct? For reference only.

1、 Turn on the sound system to play a symphony while playing the violin. Ask another person to go outside and listen to see if the sound is overpowered. As a result, among my three violins, 'Angel' was pressed into silence, while the other two could be heard clearly, 'Old Shanghai' was better than 'Bailing'.

2、 First, in a relatively empty study, close the glass bookcase, close the curtains, minimize sound absorption, and try playing the violin; Go to the bedroom filled with clothes, spread out the blankets on the bed, open the wardrobe as well, try to increase sound absorption, and play the violin. Let's make a comparison and see if the volume of the piano drops significantly when playing in the bedroom. As a result, among my three pianos, "Angel" decreased significantly, while "Old Shanghai" and "Bailing" did not.
