1, don't just watch the handwork without listening to the timbre. All handmade products are made of pure steel. The difference is that the manual surface treatment process is different. There are two main processes, one is antirust version and the other is nitriding version. Although there is only a small difference between antirust version and nitriding version, consumers still have to choose according to timbre and their own preferences. They can play handball with different techniques for comparison, and choose handball with good feel and good timbre. That's all that matters.
2. Don't buy a steel tongue drum as a hand plate. Hand disc and steel tongue drum are similar in appearance, but they do not belong to the same musical instrument. First of all, the overall shape of the hand dish is seamless, and there are eight tongue-shaped blades of different sizes on the upper surface of the steel tongue drum; Secondly, from the material point of view, although they are all made of pure steel, the surface coating is very different; For their vibration mode, the steel tongue drum is mainly composed of several tongue-shaped blades, while the hand-cranked disk vibrates as a whole shell; In addition, the handwheel is affected by its huge volume, and the sound emitted by its cavity is more empty inspiration.
3. The high-quality hand-picked vegetables are all handmade, and the extremely regular surface texture is fake. Handmade hand dishes are mainly reflected in the unevenness of the drum surface, which is the trace left by the producer's manual tuning. The pitch and sound quality of this hand disc are carefully modulated by the producer, so the price will be higher; Handmade dishes with flat drums and no traces of manual tuning are often made by machines, but the sound quality cannot be guaranteed.
Precautions:
1 is made of steel and has been improved many times. Its sound principle is more advanced. It uses spatial vibration, and musical instruments have a strong ability to imitate sound. It can imitate gong, Gamelan, Ghatam, harp, drum, bell and so on. Excellent musicians can even use it to imitate human voices.
Playing this instrument requires better improvisation ability. Even if the same trajectory is unique every time, it is completely controlled by the player at will. It has no fixed score and no fixed play. You can tap, tap or flick with your fingers. Although it is difficult to control, it is still loved by many musicians.
3. Put your hand on your cross legs, and you can make a sound by tapping with your palm or tapping with your fingers. It can also be placed on the bracket. Unlike the steel plate, the sound is softer and warmer than the steel plate. Depending on the musician's skill, the hand dish may sound like a harp, a bell or a tuned steel plate. Each "sound field" has several overtone regions around the basic sound.
