Worry-free drum, also known as ethereal drum, is a kind of steel tongue drum and a new percussion instrument that makes sound when the steel tongue vibrates. It combines the characteristics of musical instruments such as hand disc, Malimba and wooden tongue drum, which mainly rely on the tongue to drive the cavity to vibrate.
It is a new musical instrument that combines philosophy, religion, culture and art, modern science and technology, sound theory and innovative design. It not only combines the exquisite charm of classical musical instruments such as Qing, Guqin and Guzheng, but also joins the powerful penetration of current fashion. Widely used in religious Buddhism, Zen tea health, yoga meditation, physical and mental healing, not only can express feelings, cultivate sentiment, but also can heal the body and mind, enhance spirituality and discover the beauty of self.
Accuracy: The most important thing to buy an ethereal drum is to distinguish the accuracy, which determines the overall quality of the ethereal drum. The pitch of the ethereal drum produced by Lu Rusheng is about plus or minus five tones, which is within the range of professional performance level.
Sound zone: When playing the ethereal drum, if it is found that once the intensity is increased, the pitch and timbre have changed greatly, it is that there is something wrong with the sound zone of the ethereal drum, which will occur in many small manufacturers with immature production technology.
Crosstalk: If you play a certain sound area of the ethereal drum, other sound areas will also ring, so that the timbre will be mixed and impure when playing, and the original ethereal and transparent timbre of the ethereal drum will be lost.
Volume: the volume matching of each sound zone is not up to standard. Playing with the same strength, the volume of each sound zone will vary greatly, so this ethereal drum can't be played professionally.
