When hearing the crystal harp, most people may think of the tinkling and crisp crystal music. However, this association is wrong, and the material of the instrument has nothing to do with crystal. There is such a misunderstanding. Firstly, it is because the original name of the instrument, Cristal Baschet, contains the word "cristal". Secondly, it is speculated that the ethereal atmosphere of the sound quality makes people think of crystal.

The sound-producing principle of the crystal piano is mainly to rub the glass with your hands to generate vibration, and then make it make sound. To put it simply, it's the same as making a whining sound when you dip your finger in water and draw a circle along the rim of a goblet. This instrument was invented in 1952 by the French instrument makers and artists Bernard and Fran?ois Baschet brothers. Compared with other instruments commonly used in symphony orchestras, it is quite young.

The musical instrument consists of four parts. First, equal-length glass rods are arranged in a keyboard shape, called glass bows. Then each glass rod is connected to a set of upright iron rods, called glass bows. For vibrating rods, the length of the sequence determines the pitch of the sound. There is a metal auxiliary platform collector under the iron rod to concentrate the sound. Finally, several trumpet-shaped metal pieces of different sizes transmit the sound, called sound diffusers. Of course, there is also a water box under the keyboard so that players can keep their hands moist at all times.

Although it is a special instrument, the development of the crystal piano has been quite mature. It can continuously produce long sounds like a string, and it can also be used to create gorgeous sounds like a piano with a light touch of the fingertips or a large slide of the palm. . It is worth mentioning that the invention of the crystal piano happened to be at the time when "concrete music" (musique concrète) was popular. In that era of extensive use of electronic speakers and electronic synthesizers, the crystal piano was not only able to produce sounds that were in line with the avant-garde style. , is a completely natural-sounding instrument that does not require any electronic instruments to amplify it.
